Hey mate,
you got yourself a nice little case set up there!
My feedback is based on the assumption that size is like you indicate above!
Pro:
I see a good balance between key elements of modular - VCAs, Utilities, Sequencers.

Con:
Too much space consumed where alternatives are available:
- Replace Rainmaker with Mimeophon
- Use the A-111-6 instead of the A-111-5
- Maybe consider getting rid of Data but if its a must for you take a smaller footprint like the O Tool from Dave Jones

Additions:
you need LFOs, Attenuverters, a decent mixer (the Intellijel Unity Mixers are not enough), consider the Intellijel MixUp...these you can even chain and have several in a row that can grow together with your case.

In summary I think you build that case with a purpose, which is great! I think it is a great starting point.

Keep on digging!
