The specifics depend on the type of motor. But yes, that method would be
essentially foolproof.

I was going to say, "no need for load resistors or microcontrollers -
simply have the motor terminal output serve as the input to an H-Bridge".
But that assumes a bunch of things including brushed DC motors.

I bet that open source open source joysticks might exist, but reengineering
one of those to work with modified hardware might be more costly than what
you were planning to do.
