Hmm...well, maybe put a second DixieII+ in instead of the Doepfer. Saves space, which you need with that honkin' big Verbos Buchla 200 clone.
I'd also try and dissuade you from that Cwejman filter. Again, it's huge (which means it's stealing space for some other things you need) and quite spendy for what it is. You could likely get more done with two smaller VCFs, especially if you can interlink them, then you'd have room for the VCAs that you're missing and the multiples you need to spread certain CVs out.
Think smaller modules here. The devices that make sense that are large (Metropolis, Verbos VCO, Maths) leave you way less room than you need if you keep using large panel spaces. That, or scrap the rack and move up to something bigger...which might be a good idea, actually. Starting with more space and having to figure out how to fill it once your mission-specific modules are in place is usually more rewarding than hitting that cab's hp limit and then realiing that there's important bits missing.
