Well...

Admittedly, I'm no Einstein with this midi stuff but I'm not bright enough to envision how that would work.
I was under the impression one still had to have a keyboard controller for BIAB to speak to in order for midi messages/patches to play at all.

I'm no help but look forward to the responses you get to understand how that's actually accomplished.

Me.....I have (3) modules (Proteus FX, Roland MBD-1, Roland MVS-1) triggered by my Monoprice controller.

Back to it.....
