On alsa, I would do this with midiecho 
  http://www.pjb.com.au/midi/index.html 
  http://www.pjb.com.au/midi/midiecho.html 
eg: 
  midiecho -c 3 -e 3,4 -d 1 -i ProKeys -o FLUID 
 
and then set your ProKeys to play on channel 3. 
This doesn't do the "regardless of what channel my controller 
keyboard is on" bit. If you just mean for channels 3 or 4, 
then I'd start up a second midiecho client using -N 
  midiecho -N Echo4 -c 4 -e 3,4 -d 1 -i ProKeys,Keysta -o FLUID 
but if you mean for any channel 0..15 then I'd probably write 
a custom midi-alsa client using either 
  http://www.pjb.com.au/comp/lua/midialsa.html 
or 
  http://search.cpan.org/~pjb/MIDI-ALSA-1.20/ALSA.pm 
to do whatever needs to be done. 
 
If you look how important doubling is in orchestral music 
it's amazing it's not more discussed in a midi context...
