If you're like me, and 2-channel is your passion but you also want a good, satisfying, and entertaining HT experience, I'd find it VERY hard to justify the considerable added expense of running a separate AV processor and multichannel amp. You're only using the AVR to power the center and surrounds, and the MXR 720 is no slouch. It's really hard for me to fathom you using the MXR 720 in this role and being in any way disappointed in your HT experience. I'd put the additional funds into a better integrated or stereo separates -- no question. Best of luck.
