I would guess a midi router could take the controller messages from 
whatever channel and redirect them to another. I happen to have 
qmidiroute, but I would imagine PD would allow even more control. There 
are others as well that may be better. You should even be able to route 
one control to one channel and another to a different one. This should add 
little to your CPU usage as it is just looking for a byte stream and 
changing one of them for the new channel.
