A better option to this is quick swap, which is where you remove the motors screws that hold the motor front plate on, like you would if you were switching gear cartridges. You leave the front plate attached to the robot, but instead of putting the rest of the motor in with the screws, you use zip ties (or rubber bands if you’re crazy) so you can pull the warm motor off and switch it for a cooler one in between matches.
