Certainly if a motor were demonstrated which genuinely converted the field of the permanent magnets into kinetic energy, while "draining" their magnetism, it would be nearly as remarkable as a true OU motor.
NIB supermagnets can be demagnetized by forcing two alike poles together. As they approach each other, the repulsion force is strong, but after they pass by and retreat, the repulsion is weaker. Perhaps three magnets on a rotor could harness this effect: two large magnets are pulled together, a 3rd smaller one performs the demagnitizing step, then two large magnets fly apart, having gained some KE.
If this effect could somehow be used to power a spinning magnet rotor, then toy 'magnet fueled' motors could become a desktop curio.
