(I don't mean to sound like a debbie downer fwiw. This is cool.)
Sounds a bit like the GM skateboard platform.
1980's patents are probably gone by now.
In 2004 with the advent of hybrid, I tried to patent a triple-rotor electric motor.
It used a variable flywheel between two sets of reaction surfaces.
It eliminated counter-torque for pure efficiency.
In disk form (the most torque-efficient configuration similar to a cheater bar), the motors were completely stackable.
Add more for more power wherever space allowed.
Remove the bad one from the stack easily.
