Request for feedback on integrated wheel-propeller hub mechanical design for a transforming drone project (referencing ATMO paper)

A developer without a mechanical background is seeking mechanical design advice on Reddit r/robotics for an integrated wheel-propeller assembly in a transforming drone project: the outer wheel is driven by a timing belt and pulley, the central BLDC flight motor remains stationary, and the motor's three thick phase wires must route from the center of the wheel assembly back to the chassis without tangling during ground travel. The attached image shows a structure from the ATMO research paper, and the post asks how to implement this "fixed inner core, rotating outer ring" mechanical stack in CAD.
