Not bad for a basic runthru...now, I'd suggest starting to pare this down. See what you can remove but still arrive at essentially the same sort of functionality. Also, are there modules that allow you to consolidate the functions of several discrete ones in this build into one or two in the next? Can you increase the functional density, but reduce the physical? Start with those questions first.
As for substitutions outright, one I would strongly suggest would be to remove both the Vermona and Doepfer MIDI interfaces and, instead, install an Expert Sleepers FH-2 + the FHX-8 expanders. That drops your MIDI interface footprint from 30 hp down to 16...cutting the space needed by nearly half, while upping the outputs to eight CVs and gates, plus another eight assignable outputs and two inputs, adding internal pattern gens, arpeggiation, and two return channels to allow you to master-clock your DAW from the Eurorack. Now that's what _I'm talkin' about! Keep applying that sort of logic to module choices, and you can almost double what this could be capable of while making it maybe 1/3rd smaller!
