Explain the drive being jumpy?
For demos, you could switch to a less grippy wheel, so the drivetrain won't be stressed.
I don't believe you want to drive two motors that are connected together with different values. That will stress the driven motor more. We also had a situation where we tried to calibrate one of the victors on a drivetrain with the other disconnected, and blew out the disconnected victor, but I'm not sure that's related, but given the price of victors it's an experiment I don't want to repeat.
If you really want to try driving just one motor, I would either drive the second at a 'reduced' PWM value so it will be coasting, or make sure the brake jumper is not set on the coasting motor.
Can you post a picture of the chassis? Is it possible with the cantilevered axles there is flexing that is causing the mis-alignment? Are the chains near the frame, or on the other side of the frame/bearings?
