I guess I'm not sure why you need neutral in your framework, rather than say, just physical as the basic stuff with qualia as higher-order properties of physical in consciousness.
Yeah, and that's the point, there are varieties of 'neutral monism' that are best classified as varieties of physicalism (and thus already exactly doing what you say -- physical as the basic stuff with higher order qualia) -- there are varieties of physicalism that more or less say the so-called quantitative properties that we associate with fundamental physics theories do not reveal the full nature of the physical properties we need to include in our full ontology, and that this full nature is neutral. Neutral between what and what? That's where one has to be careful to avoid confusion.
The neutral is not neutral between the ultimate-physical and the mental so much as neutral between the properties revealed to us via qualia and the mathematical properties described in fundamental physics via present-day methods. So there are varieties of physicalism that are basically already neutral monism...but this is important to distinguish because there are varieties that don't accept the robust reality of qualia.
Just to give an example of what this looks like -- we might say to find the full nature of the mysterious wavefunction of quantum mechanics requires investigating properties that are of quite different a nature and deeper a nature than we've been able to as of date.
I tend to think the most plausible answers are some neutral-monist-flavored variety of physicalism. The alternatives are the ones that often say qualia are essentially illusory, and these acknowledge that they don't see how fundamental physics would explain them using existing techniques, but they say the solution is deflating qualia in some way. How much they deflate qualia varies.
Of course, I'm still tentative and open to all approaches
but I sort of default to the approach that seems consistent with the hardest-to-deny data, and that's that physical science works marvelously well, and qualia seem robustly real. Either can be denied, we can be anti-realists towards either, but it's the sort of thing where I start off thinking they're likely real and then try to see if there's any incoherence to either.
I'm very open to reconceptualizing qualia significantly, but it seems that will just lead one away from traditional physical science, as if anything, to introduce into our ontology something fancy enough to truly reconceptualize qualia on deeper grounds seems to promise disturbing the bastions of tradition.

Presumably, if your basic stuff is neutral stuff, that's not physical stuff; or do you mean that the neutral stuff is equivalent to physical stuff?
This goes back to what we said earlier, which is where you asked 'why call it physicalism' -- well because what if we really think charge, mass, etc are the fundamental properties of the world but just believe their nature deeper than what our mathematical models have told us, and that this deeper nature can account for the emergence of qualia?
Again, neutral not between physical and qualia, but rather between the epistemic, not ontological notion of physical (i.e. physical-as-far-as-we-know vs physical-as-it-really-exists-in-reality) and qualia.
Basically this is a variety of nonreductive physicalism.
