Tossing my 2c in, I wonder if there would be enough separation between the ceiling and surround speakers, given the height the surrounds will be at? I use both Auro-3D and Atmos, and I think they would both be effected quite a bit.
Also, angling in (2) M3s from the rear corners for a 5.x.4 setup might work out better for the room shape and seating, and you wouldn't need the extra amp.
I've found I prefer QS8s over M3s for surround, even though counter to specs.
Edit: Final thought, if you used on-wall M3s you might be able to mount them flush in the rear corners, closer to head level. Since they have downward facing ports, that wouldn't interfere. Not only would you be following the Atmos angles for surrounds, you would also have good separation between your surround and height layers. 5.x.2 with zone 2 maybe?
Looking forward to seeing how you work it out.
