what exactly are you trying to do?
what do you mean by redundant? "functional duplication" in modular is often a very good thing
currently you seem to be quite modulation heavy - tetrapad/tete/quadrax/planar, melodic sequencer and adsr channel heavy - metropolix is I think 2 channels (and you only have one vco!) and you may not need adsr envelopes = the intellijel dual adsr is huge compared to similar modules from other brands
no vcas????
rainmaker is too big, imo, in a single rack like this unless some compromise is made with other modules being smaller than they should be (and I don't think you can do this in solely intellijel)
so you almost definitely need to add a quad vca and another vco - which means 20hp+ if you want to stay intellijel only (personally I wouldn't - I hate constraints)

a art dream machine that can do sounds above your imagination but also minimal techno or ambient shit :D
i think that should work^^
other module builder dont fit in the esthetic... maybe mutabel instruments and alm buiscuit....
