That’s a lot of decision making to leave up to other people who don’t really know what you like or what you want to get out of your modular. But you did ask what we would do…
For myself, in that size I would rely on external sequencing, control, effects, and sampling – concentrating specifically on synthesis that can’t be done easily in a DAW.
So the core of that, to me, looks like: Orgone, Rings, Telharmonic, Maths, Streams. Probably O_C for Hemisphere since it’s a bundle of useful utilities, though you could replace it with a uO_C which is 6HP smaller and has a better layout. Maybe keep SMRF, Zorlon, Honda and/or Clouds. I’m not familiar with everything on the list but there’s still a little room to play with.
And then I’d want a Stages for more modulation, a versatile filter (Belgrad/Sisters?), more VCAs (Veils?), perhaps a matrix mixer, a pedal interface.
