Thanks for your time and input.
Unless I'm envisioning this incorrectly, it sounds like you would end up with what is already the Dolby 5.x.4 setup, or something reasonably close, no?
Even if the sides were closer to 90 degrees, I think you'll likely be O.K. I do have a 7.2.4 setup, but often run in 5.2.0 - which leaves the sides in the 7.2.4 physical location (and mine are even a bit forward of the MLP) - and it still sounds excellent. Maybe not AS good as if it were a "properly" placed 5.2.4, but still delivers a convincing performance as far as sound location goes.
I think you'll have a better experience with a 5.x.4, vs. a 7.x.2, just my opinion, but do try to land the ceiling speakers as close to the Dolby recommendations as you can. Being that the placements for a x.x.2 and x.x.4 are quite different, hard to experiment without leaving at least 2 big holes in the ceiling, unless you do on-ceilings, then maybe small holes. Otherwise, I'd say experiment with it.
The receiver will EQ the speakers based on their physical location of course, but it won't work magic as far as sound placement, right? Two different things. The algorithms do operate off of certain assumptions, like proper speaker placement, so you do want to be reasonably close, doesn't need to be dead perfect. I mean, easy enough to test - just leave the sides where you need to, turn off the rears, and push 5.1 material to them....how does it sound? The right and left side surrounds do not need to be placed in a spread equal to the fronts by the way, which I think you indicated in part of what I did not quote.
