If you are reffering to the pilot vs. co-pilot view option, that is possible to be changed by intallsation of new flight panels.
Currently, there is a very good FO panel for 737-400 series, and it is boundeled with Virgin Express and Southwest airplanes (freeware, you may find it on AVSIM.com or FlightSim.com data library.
If you're reffering to co-pilot operations and procedures, I am not sure if that is possible.
You may compile advantures with APLCC utility that would automatize co-pilot's actions based on interaction with virtual ATC (within adventure).
