YOu can still use the QS8's with a ceiling mounting bracket that will lower the QS8 from the ceiling. I wouldn't recommend using M3s in the ceiling, as they in-wall speakers just weren't simply designed to hang like that.
Also, by rears you mean "sides" right? are running a 5.1 or 7.1 system? If 5.1, your "side" surrounds should be at a 90 degree angle to your listening position, or perhaps 1 or 2 feet back. But by no means should they be on the back wall (unless you have no other choice).
