Can't the encoders still be connected to the Jaguar?
The only rule restriction is that commands must come from the cRio.

The cRio can read the position (or speed) from the jaguar.
PID (or other closed loop control) can be calculated on the cRio.
Then the calculated voltage can be sent to the jaguar.
