No list suggestions, but one technical one: try and keep things dealing with audio away from the power supply. That area is fine for modulation sources, CVs, etc, but if there's a bit of noise on your DC that creeps into the P/S, it can also sneak into the audio paths. The MScale, buffered mult, and MIDI interface are fine, but you might want a little more distance for the In/Out and the A-119, especially since both have preamps that can boost low-level audio. Otherwise, this is looking pretty damn good!
