Using OB to poly-chain A4/AK

Maybe this is a feature request, or maybe it is an inquiry as to if is currently possible?

Is anyone using OB with 2x A4, or 2x AK or A4 + AK?
I wonder if it is possible to set up a “poly-chain” style configuration using OB to route the Midi notes and midi encoder output from one A4/AK to the OB plug-in that controls another A4/AK?

I reckon having them setup with the same patch library to start would help, too.

Has anyone tried? Perhaps some Max4Live midi trickery is also in order.

PS. I’ve been able to send midi from my A4’s encoders and keys to my Rytm, via Overbridge + Ableton Live External Instrument plug-in to assign in routing the midi.
