I don't think it's viable. If the play/record is recording actual motor output, that would depend on the voltage of the battery at time of recording. If it's recording desired output, PID wouldn't be viable as the actual output is updated every tick, meaning the PID has no effect. Unless you've got a master control loop running at ~100-150Hz, it wouldn't do much, and even then, you'd see a lot of jitter.
