power transmission NOT using gears/chains?

Couldn't you establish a correlation, in programming, between the output values of your high speed motor and your high torque motor?

So, rather than operating the high speed motor at near-stall loads under 12V, you could 'artificially' slow it down by applying less voltage via the program.

The free-speed we associate with each motor is for 12V only. If we reduce the voltage to the motor, we reduce it's free-speed. So, if I understand how this might work and what you are saying correctly, it's possible, I think, to make it so the high-speed motor sees little load at low speeds by matching it's potential free-speed to the actual speed, under-load, of the high torque motor.

Does that make sense?

Edit: I really like this idea.
