I really like the Xaoc Devices Sewastopol, envelope follower and trigger/gate generator!
It tale a little bit to dial it in to suit your playing style and I have never tried it with a wind instriment, but I don't see why it wouldn't work.
You can also use more than one input module at the same time for multiple signal processing options.

Other than that, I would want some way to loop audio so I could layer up in a more traditional manner than the Morphagene. This may be better done in a foot pedal?
I like that you have plenty of VCA and Mixer options, but it seems you need more modulation sources perhaps?
I don't ever feel like a modular system is complete without a robust clock source. Pam's New Workout can be had for a song these days or Pro if you have the cash, both are excellent!
It seems like a fun project, I would like to hear how this sounds one day!
