Eric, I'd also suggest that you use the QSs at least for the side surrounds. I wonder if your preference for direct firing is in comparison to dipole surrounds. If so, note that the QSs aren't dipoles; all the drivers operate in phase. They're a variation of direct firing which results in much more spaciousness and to a considerable extent combines the best aspects of monopole and dipole surrounds.

If you have enough room(say 7-8')between the listening position and the back surrounds for the monopole speakers(most likely M2s)to disperse their sound, they can work well, but even in that situation QSs wouldn't be inappropriate.
