Well, I'm not Lugia, but here's how I would probably set this up to start with. Of course I would tweak it as necessary after experimenting.
I tried to keep the plumbing along the sides and separate the 2hp stuff a little bit for wiggle room. I would probably want all of my clocks/gate sequencers along the bottom with mults above so you could mult gates around the system. Modulation and matrix mixer just above the sequencers. Links at the top left for a buffered mult/adder near your oscillators. Sound sources, filters, drums, FX, and maybe VCAs all grouped together with other mixers and attenuators sprinkled throughout. It's always hard for me to find the right spot for Disting, so the top right of the case seems to work here.
This seems more organized for the way I work, and the way my own rack is set up but obviously this may not be a sensible approach for your workflow. Either way, it was a fun exercise.
*edit: I placed Marbles above the other sequencers due to the jack placements.
