Let's pretend that you knew what you were doing.

Sure, I do that all the time.

How would you use your
sails to turn a normal fractional-rig sloop aft to wind while on a
mooring?

I would pay out more line, say 600' or so, then backwind the jib till the
bow starts turning downwind, set the jib and steer downwind. Easy, eh?
