Hi Jim,
Thanks for getting back about this!
Ok, so here’s my scaled-down version: 
I kept the Dust of Time, Beads, Maths and Chaos modules and added the Marbles instead of permutation, because I think it does actually look more interesting (knowing that I won't know until I really touched it).
I also exchanged the veils etc. clones for the real thing - could you explain what exactly makes them better? Is it the build or sound quality?
I’m still somewhat confused about the utility modules… like, how many I’ll need for what. And I’m uncertain if I have enough VCAs and whether I need an envelope generator.
About case, I am planning to build my own, so that should come much cheaper.
