A couple things: I second Jim's recommendation against the Instruo matrix mixer. Would recommend something like the Doepfer one at first, though it is much larger.
Also, you have way too many compressors here. MSCL, Messor, and Ghost? I imagine you want sidechain functionality which can be done in a modular fashion with an envelope follower/inverted envelope and VCA. If you want "character" compression, maybe find a single one that appeals to you most. For "character," I've really been enjoying the SSF Vortices mixer. It's subtle but awesome, but you can do feedback patching to get even more grit and character. I handle more transparent compression outside the rack.
Good luck and have fun!
