I've done it before. It works fine. If you have good friction between the prop and backplate, it really doesn't take that much torque to hold the prop on. If you're using a plastic backplate, cut a piece of open mesh sandcloth (the stuff you use for drywall or plumbing) to make a washer between the prop and backplate. it works so well you won't be able to make the prop slip even with the prop nut only hand tight.
