The detangler gizmo will NOT take the current of the drive motors but you're on the right thinking track. You'll need a set of slip rings and serious motor brushes from car motor. It's sort of like a motor commutator but instead of the three segments you use two full circle rings with a brush on each. In practice I'd tend to use two brushes onto each ring just to handle the current better through the running contacts.

Yes there will be some torque through the rotor bearing that goes into the body. You'll still need a tail rotor but instead of it pushing constantly it could be a small motor that goes on and off with a reversable power to push or pull as needed.

The tilt rotor in this case will work semi well but you'll want to put most of the heavy stuff in the bottom of the fuselage to assist with the pendulum effect. Otherwise trying to tilt the rotor will just tilt the fuselage. It'll still tilt as the rotor moves but with a tall shaft and low CG it shouldn't be too bad.

Will it fly? Not a clue. With this being a simple fixed rotor planform it may have "issues".
