For generative? One thought: it's too small. Another thought: why are there two buffered mults in a rig that really has only three "oscillators" (one of which has input buffering)? A third: where are the filters?
This isn't going to work for the purpose you're aiming for. Proper generative systems involve A LOT of modulation sources, various ways of altering timing structures, plenty of ways of combining and interacting between modulators, and a rather extensive but generally uniform set of audio paths. For example: there's two VCAs here, but the 2180 VCA isn't one that can work with CVs or modulation signals. It's not a DC-coupled linear VCA, and instead, it's one primarily for audio work. Cool beanz for audio...but if you want variation with your modulation levels, that won't be happening here.
While the addition of a tile row (and, IMHO, the correct sort of tile row...sorry, Intellijel!) is a really great idea for moving basic utilities out of the 3U turf, this rig isn't where it needs to be overall. For one thing, you're trying to use a very small cab for a "big cab" purpose, and this never works well. Secondly, there's lots missing. My advice would be to start over...and if you're intent on doing proper generative work, you should start with a case that's several times this size. In fact, that advice goes for ALL builds; NEVER start in a small case, but instead, start very large and pare down from there to the point where the functionality you want is just supportable. THEN resize the case.
The other thing I would suggest would be to get a copy of VCV Rack. Work out your generative ideas in there, then start figuring out how to transfer the ideas from that virtual Eurorack environment to a real one. This should not only give you a much better idea of the scale you should be working on here, but a very clear idea of what sort of modules this needs, what sort of actual outlay is involved, etc.
