The mono camera however, can be pure Ha with a Ha filter. If I make a OSC stack, and a Mono Ha stack, and register them together like I would for a pure narrow band composite, is there any reason they cannot be layered together in PS?
Hmm, maybe luminance as well.

No reason why not at all
Below is a sequence of ngc 6164
done on a canon
straight RGB
Ha RGB
Ha Oiii RGB
the antennae galaxy was a mix of old RGB data from my canon 600d and a few subs of luminance from my QHY22.
I use RegiStar which figures out image scales and orientations. makes life way easier. as you know we are talking about different sized images. but i also need to use PS.
edit: found the original canon antennae with no luminance from the qhy22.
