Close to 100%. All you have to do is figure out a way to make that gear behave.

Mathew Murray did it in 1802 so it does work - http://www.homemodelenginemachinist.com/f14/matthew-murrays-1802-hypocycloidal-steam-engine-7720/

I recently ask the question about altering the movement of a crank to lower the volume of a stroke and possibly maintain or increases the torque.I would imagine that something similar to this design may work,egg shape on the outer gear maybe.
