I know!!! those weird angles are driving me crazy!
The deeper into a cutout and the less space around the speaker, the worse it's going to sound. Specifically, it'll start sounding like the sound's coming through a tunnel, which it essentially is. Certain frequencies will be harshly emphasised, while others will be muted. It might get slightly echo-y. You'd have to set them pretty deep in there for it to sound "horrible", though. Ideally, if you could size the cutouts to exactly the speakers size, and push them right to the front of the cabinet, maybe even overhanging a little bit, it won't sound too bad at all. As you say, it's just not recommended.
Personally, if I were you, I'd be looking at doing this:
Get the 3 fronts into the "shelf" area by rotating the tv to give it space on both sides. Get a short centre, maybe raise the tv up a bit if necessary. I'd probably do an articulating mount there, really. Get the speakers as wide on the shelf as possible (safely) so that they don't block the tv. Then I'd do 3x in-ceilings for the surround channels, and just to fill out sound in the space for when I'm doing "party-mode" music rather than serious 2-channel listening.
For the sub, although it's "omni-directional", I still find it can be distractingly localizable if it's not in the generally "front" direction. It's just a weird effect when all the rumble is coming from behind you. I'd probably try to do dual in-wall subs on the two faces of the console there. Maybe even on the top, to leave room for the receiver below.
