What happens if you make use of both action and reaction forces?

I think if you look closely at the physics of it I think you will see there is no gain.   You would be seeing half as much output power on each half as you would if the motor was mounted down to something.   The relative RPM in either case should be roughly the same except in the case you are showing you would also be adding resistance of the motor casing spinning in air as well as additional power needed to spin the larger outside motor casing.   Thus the stationary mounted motor may actually produce more overall power.

Thanks for the reply.

I agree that total power may be distributed on both rotating masses.  But it will not be in terms of RPM because both rotor and stator attain tremendous speeds.  Power distribution will be in terms of torque (Force X radius).  Greater the speed, greater will be the back e.m.f.  induced in the rotor reducing its torque.
 
Hence at lower speeds power may be distributed equally on rotor and stator but at higher speeds back e.m.f. induced in the rotor  will be high which reduces its torque and you will get maximum torque (hence power) from rotating stator.
 
I think we can gain from this setup by using a greater diameter rotor and stator.  At the end of longer radius, the force required to get greater torque (hence power)  will be less due to mechanical advantage.  Even a small force will set the stator in rotation since it will be rotating at longer radius producing greater torque at the center.

I don't think that you have to fix the batteries on motor casing.  Fix one more slip ring on exposed portion of the rotor shaft, insulated from the shaft.   Connect the motor terminals to this new slip ring and supply power to it from batteries held fixed somewhere on ground.  Rotor will rotate in one direction and stator will rotate in opposite  direction.
