Is there any part of the motor that would react to heat, or cause the stall to lower while the motor is warm (not the internal sensor, possibly resistance increases?)

The motor has a PTC the stops the motor when it gets too hot.
Running a drum off the motor will cause a higher torque needed to move the load as the drum gets larger.
I think a second motor and some fans might get you by the match. If you are drawing 10-12 amps a second motor would drop you near or below peak efficiency for each individual motors. Coupled by fan or two and you may find that it runs well.
