Is a friction drive planetary set really feasible? I picture you having
to control temperature very carefully to keep a common friction line
force. Seeing as we are talking about mounting the sun gear to a shaft
attached to a turbine that a wankel is breathing over.

The Paxton design was more of an epicyclic like set up wasn' itt?

The torque is so low a non metalic coupling could be used to
decrease the heat transfer. The wheels are spring loaded together
to compensate for temp changes.

30 HP at 100,000 RPM

HP = Torque X RPM / 5252   HP x 5252 / RPM = Torque  1.57 foot pounds.
