Looks like a really well designed case! Some people would say the point of modular is to create your own instrument's ethos instead of following that of a single manufacturer; but actually the point of modular is to do whatever you want. The Intellijel ecosystem is very robust.
A couple notes from my perspective:
- I think you're right -- ditch the 1u effect. A noise/random source would be good (though I think Pam's can do some of that too, so you're not totally without as is? I don't have one so I'm not sure).
- In general where I think you lack is CV utilities -- you can generate a fair amount between Quadrax, Tete, and Pam's, but you don't have a lot of options for mixing/scaling/offsetting let alone folding/comparing/rectifying etc. I wonder if you need all of Dixie/Morgasmatron/Rubicon: you've got a lot of voices for a small system. I'd maybe ditch either Rubicon or Dixie, and this is where I'd consider stepping out of the Intellijel ecosystem for a compact, CV toolbox type module and, if you have the space, a dediciated LFO (either complex, Batumi-style, or freeform Ochd-style, depending on your use) module perhaps.
Hope this helps. Happy Holidays!
