Some thoughts:
1) I think I'd swap the Nin and VCF3 for an analog oscillator, maybe an Instruo Ts-L. IMHO Nin loses it's oomph in a generative rack, and you don't need three filters, so an analog oscillator (always a nice thing to have around) is a nice replacement that can help create some contrast with Plaits and Rings.
2) I like Cold Mac, but for your purposes here I'd probably just get a Links and Kinks, they do a lot and it's all grok-able.
3) Rosie seems too big for what you're aiming for here, I'd replace it with an ALM HPO which gives you 6 more HP.
4) Since the quad VCA cascades I'm not sure you need the mixer. I'd pick something interesting like a wavefolder or distortion module (Instruo Tanh or something from Noise Engineering maybe), or pull some more effects into the rack like an FX aid (a common recommendation).

Hope this helps!
