We are thinking about making a winch spool that has two pins sticking out one end, and a pin going thru the motor driven shaft that will engage them. The spool will slide sideways on the motor shaft (driven by a fork in a collar, powered by a small pneumatic cylinder) to disengage the spool from the shaft.
We haven't built it yet, so don't expect it to work...but it looks like something we can make without too much trouble.
