I'm not a member over there, so for now I put a couple comments here. Yes, things get lots easier if you don't use the ARC amps at all, but I'm sure they are the better sounding option. If you want to use them, I wonder if you could build a rack to stack the two SE amps (with a 0.5-1" air gap between them) and put them where the styrofoam tray with the inflator equipment sits, and still have them below the height of the floor mat? Then you could mount the XDi amp in the left side well on a board bolted to that diagonal sheet metal brace. If you want to also have the Toros in there at the same time, you might be able to stuff them on top of the two wheel wells - they look pretty small. You could maybe build a board for one or two of them stacked and use some kind of adhesive to attach it to the smooth top of the wheel well. The nice thing about Class D amps, besides their compact size, is that they run cool.
