Wow! I like where you're going but that "gearbox" part will add up to be mechanical losses it sounds like.
Something like this?

Yes something like that.
Maybe if two squirrel-cage rotors rotate in different directions in one stator, they will compensate for the back emf ? Even if this does not happen, maybe such a motor will find application somewhere.

These shaded poles are found in microwaves. But usually the rotor does not have magnets on the rotor and they work on eddy currents.  The ones without magnets can spin in either direction once you remove the big wire.  But since the rotors have no magnets, rotor induced Back-EMF is practically non-existent, except for the back-EMF produced in the coil.  But my guess is it should be possible to get 2 rotors spinning in opposite directions with the eddy type rotors. But to what avail?

If you add magnets to the rotor, then my guess is it will be near impossible to get both rotors spinning in opposite directions with symmetrical magnets on the rotors. You would need to reverse polarity of the magnets on 1 rotor to get them to spin opposite directions. Then I am pretty sure the Back-EMF would just double as if the prime mover were spinning 2 rotors. 

These are just my predictions.  But I encourage the build to know for sure.

I beg to differ. Huge currents are present in a squirrel-cage rotor. It is they who force the rotor to interact with the stator.
Of course, I am not such a specialist in electric motors as Rakarsky, I could be wrong.

You may be right.  It would be very easy to test..

1. Apply AC to the motor and let it spin and notate the driving power.

2. Then remove the rotor and just power the coil with the exact same AC source.

The results should tell us with good certainty how much Back-EMF the spinning rotor added.

I have a similar motor with an easy to remove rotor- so I may test this in a bit
