What is trhe idea of your rack ? Are you planning to live sample and resample in the Bitbox ?

Otherwise, I would actually use Nerdseq for most modulation duties, remove some modulation.
I would also probably remove the tuesday. You have a lot of sequencing power in there, and not many voices.
Also there's no filter.
What about adding a small footprint osc (Noise Engineering ?) and a filter (Joranalogue Filter 8 is very versatile) ?

On the 1U, an interesting choice is a ornament and crime, or some LPG.Maybe a 1U oscillator, that you could use for modulation ?
