My approach would be like Neutral Monism in two respects:
(1) Consciousness and matter arise from a background that is neutral, i.e., it's neither consciousness nor matter.
(2) My approach denies that consciousness and matter are two fundamentally different things, i.e., my approach denies ontological dualism.
A lot of questions packed into this paragraph. I will try to answer them.

When you say arising from - this suggests a temporal order and a dependency of matter, in fact an identity of matter with consciousness - matter is what we see when we look at external reality - so that matter and mind are not fundamentally different - the temporal order is first neutral substrate, then consciousness...
Yes, I do mean to imply an order or hierarchy. The order goes as such: neutral background, consciousness, matter
Yes, the existence of matter is dependent on consciousness. One has to be very careful to understand what I am saying here. The following quotation--which I had actually been trying to track down for some time--captures the situation very well, I believe:
"Discussing the play, John H. Marburger III, President George W. Bush’s science adviser, observes that “in the Copenhagen interpretation of microscopic nature, there are neither waves nor particles”, but then frames his remarks in terms of a non-existent “underlying stuff ”. He points out that it is not true that matter “sometimes" behaves like a wave and sometimes like a particle... The wave is not in the underlying stuff; it is in the spatial pattern of detector clicks... We cannot help but think of the clicks as caused by little localized pieces of stuff that we might as well call particles. This is where the particle language comes from. It does not come from the underlying stuff, but from our psychological predisposition to associate localized phenomena with particles.”
What is matter? Matter is a
subjective perception. Matter is a
subjective concept.
It is conceivable that there exist organisms on earth that do
not perceive reality to be matter/material. They may perceive reality to exist in a form completely alien to us. Indeed, there may exist non-terrestrial organism that likewise do not perceive reality to be material--consisting of particles or waves. And perhaps they don't conceive of it that way either. Perhaps their way of perceiving and conceiving reality is completely alien to our material way of perceiving and conceiving of reality.
Matter is a perceptual and conceptual map of the territory that is external (i.e., non-subjective) reality.

an identity of matter with consciousness
The "identity" between matter and consciousness is like so: matter is to consciousness as map is to territory.
>>
matter is what we see when we look at external reality - so that matter and mind are not fundamentally different
When a submarine turns its sonar on "external reality" it sees red blobs on its radar screen. We would say those red blobs on the radar screen are a map of external reality, however we would never say external reality just is red blobs.
Likewise, when we turn our perception to external reality, we see matter. However, most people do say reality just is matter. This is a mistake.
However, just as the red blobs on the radar screen and the external icebergs floating around the submarine are not fundamentally (ontologically) different, neither are our perceptions and external reality constituted of fundamentally different stuff.

how and when does consciousness arise from a neutral substrate? - if it is neutral why does consciousness and not matter emerge from it? How does something neutral give rise to anything?
If we say that (a field of) consciousness just is the most primal substrate, then we are left with the same question we ask when we suggest that matter is the most primal substrate: Why is there something instead of nothing?
At the end of the day, I believe there are deeper processes underlying the emergence of consciousness.
>>
How does something neutral give rise to anything?
The background is neutral in the sense that it doesn't favor consciousness or matter as being primary.
The Hard Problem is getting consciousness (feeling) from a material background, a background of "figures and movement." While it certainly is beyond our ken as to how consciousness could emerge from a non-conscious background, it is different problem then getting consciousness from a material background.
>>
What is external reality? The neutral substrate or consciousness?
Reality just is (a field) of consciousness. Individual points-of-view or
subjects differentiate within this field of consciousness. (I don't necessarily like using the term "field" but I think it works as a temporary conceptual scaffolding.)
When these differentiated subjects perceive other subjects they perceive them to be objects/matter. So external reality is the field of consciousness external to the differentiated subject
from its point of view.
Another way of thinking about this is a system of systems. Reality just is one big system and subjects are sub-systems within the system. They are all one super system but individual sub-system will view the rest of the system as external from their pov.
>>
How do you solve the combination problem that takes subjects from "consciousness"?
On this view, subjects don't combine but rather divide. That's a rather crude way of saying that this background field of consciousness differentiates into subjects (and sub-subjects).
>>
If consciousness is external reality, why do we look back and see "matter"? Why not see consciousness as it is? Why not just have consciousness look back against its self?
When a subject perceives reality it does so in the manner outlined by Strawson. As we've discussed, this is the most direct perception can ever hope to be:
Stimulus X evokes change X1 in the organism.
Simply put, we can't
perceive reality as it really is. Perception is a process of exquisitely complex state changes occurring to the organism when it encounters various external stimuli.
This is how sub-systems perceive other sub-systems within the super system.
"In the tenth century, Ibn al-Haytham initiated the view that light proceeds from a source, enters the eye, and is perceived. This picture is incorrect but is still what most people think occurs, including, unless pressed, most physicists."
