You've severely limited yourself here. This build is too small to support something like the SV-1 without making serious compromises to other subsystems that should go in here. A far smarter mover would've been to study the SV-1, then obtain the "primitives" behind its panel as discrete modules. As it is, your rig here is now being "forced" in terms of operating capabilities by that one module. This actually negates the point of modular...YOU should determine how things function, not some particular module.
Also...why do this sort of setup in general? 2 x 84 is pretty limiting as well. I note that you've got a uZeus in there...so why not jettison it AND the 2 x 84 and go with a Tiptop Mantis? You'd have 40 more hp to work with, the rack is prepowered so no need for the on-panel supply, and it has proper filtered power bussing...no flying busboards! But even if you go with that (IF you can change your order ASAP!), the SV-1 is still a no-no, as even 2 x 104 is too small for a big honker like that.
