a couple of things to point out here:
plaits is dual mono not stereo - it has 2 outputs, but they are variations not stereo
warps is also not stereo - possibly it is in some modes - it has 2 inputs (carrier and modulator) and 2 outputs (the 'normal' output and a vca'd aux output which appears to be a mix of the input and the output) - again that doesn't make it stereo - just 2 output channels - and I'm not sure how modulating one output of plaits with the other will work in practice - if I had warps i would try
so maybe a better signal path would be both plaits -> veils -> warps -> qpas (for filtering and stereoisation) -> beads (insert more vcas as appropriate)
I'd probably skip the NoiseRainbow2 - kinks has 'noise' and marbles has a random output (Y) - probably enough in this size case
I'd probably also remove the quadrax and expander - I think that Pams and Maths should be enough modulation sources for this size case - but I would want more mixing capabilities - probably a matrix mixer, specifically for mixing modulation sources together - choice is limited by space though! and/or another quad cascading vca (take the dual out and replace?)

Utility modules are the dull polish that makes the shiny modules actually shine!!!
