This looks like a fun little rack that would fit an attitude of exploring creativity within constraints. Beehive/Plaits doesn't need a filter and sounds great on its own so that's a good choice. If you run Hemispheres suite on the uO_C, you've got quite a lot of modulation and utility possibilities here. One downside is that none of the modulation parameters are very 'hands on' in this system -- you will find yourself wanting to tweak an envelope shape or LFO speed in real time at some point, not just their amount. You might consider swapping the FX Aid XL for some small modules that provide or facilitate modulation, e.g. Pique or Kinks, or even a small analogue oscillator that doubles as LFO. Disting and Monsoon should, I believe, provide enough effects. The 2HP Trim could be replaced by a 2HP VCA.
