The problem is possible requirement of strong interaction at short distance with forces of several tens of Newtons while still maintaining the delicate levitation/stability. I don't want to play with larger magnets because when they become unstabilized can fly away in random directions and when meet iron furniture, materials or other magnets it get damaged.They are expensive too, to trash them few of them in a session.
Lately I tried to find spin lock while spinning the floating magnet in opposing direction of the base magnet spin using compressed air. There was no problem on spinning up the magnet while floating but when it reach a critical high speed while seeking the lock, possibly a resonance happens (It can be seen a precession like motion for an instance) and the magnet fly away with high speed using the kinetic energy of its high spin.

If there is any possibility of creating a macro self-powered effect using the interplay of magnets, selective application of torque, and gravity - such as often claimed with the infamous “magmo” designs which never quite get there … it will likely exploit hypotrochoidal geometry - instead of simple rotation.
