you don't need a mutant brain for a BSP to talk to a modular - it's got cv/gate/velocity and trigger outputs already...
I would recommend a lot more research and thinking before spending any money - a couple of pointers:
in the first iteration - Pams can do euclidean - so not a lot of point with the euclidean circles too
in the second there's a melodic quantizer - scales, but no melodic voice or vco to use it to send quantized pitch to... and only the scales for pitch sequencing - I'd get frustrated with this...
how are you mixing? sub mixing before filters/effects and end of chain? ok I see the cockpit2 - but that's not really going to do a satisfactory job - spend some time thinking about how all the voices and effects will interact... are any stereo? do some mono sources need panning into a stereo field? no mixing for cv...
no vcas... why would you want/not want these?
I'd rather have a second fx aid than a pico dsp - awkward size 3hp and less versatile - but I don't think you need it, anyway...
take out everything except what you absolutely need and then add back slowly, justifying precisely why you want/need every module - ie do I need this and why?
take a look at my signature and ask yourself why? you've got way too many sound modifiers and possibly modulation sources - not a balanced rack even for a percussion rack - & I'm not sure that's 100% what you're after here - seems more confused than anything else

Utility modules are the dull polish that makes the shiny modules actually shine!!!
sound sources < sound modifiers < modulation sources < utilities
