Do you have room to install a collar, with a small disc for a cable
actuated caliper of some sort. Like a bicycle brake, only larger.

The collar would probably be easy although there is nothing available
off the shelf that I'm aware of. The difficult part would be creating
a secure attachment point for the caliper. Given the forces involved,
the caliper itself would need to be hydraulically actuated like a disc
brake.

Motorcycle disk brake might be most adaptable.

I'd feel safer if the brake disengaged if the engine powered up or
something's going to break some time.

Quick thought: airplane "parking" brakes and mid-80s Subaru clutches
hold pressure until the brake (or clutch) is depressed. Perhaps the
transmission's hydraulic pressure could be tied in.

Feathering prop is probably simpler, easier and cheaper in the long run,
and it's proven technology.
