Yeah, now...that new iteration is making a lot more sense...at this point, the only two things I'd do would be to add some more modulation sources, preferably something that can do double-duty as an envelope or an LFO, like a looping AD. I'd also consider adding some simple DC-coupled linear VCAs so that you'll have those for manipulating modulation signals. EMW's Triple VCA is about the right sort of thing for that, and as for the looping envelopes, either Intellijel's Quadra or Qu-bit's Contour would be a decent fit, and you've got the space for both. It's turning out pretty decent!
