I had a 1/4" S-K round head rat with a buggared handle. Mechanism was fine, but the handle was unuseable. Figured it was a worthy contestant for a home-made palm rat project!
I cut the handle off right below the head, press-fit the head into an aluminum thrust collar, then formed a teardrop-shaped ring out of stainless and epoxied the mechanism into it. A final coating of plasti-dip and the thing was done.
Came out much better than I expected, and works darn nice, too! Use it almost daily, and I can use any 1/4" drive attachement (swivel, extension, etc) and easy to find sockets.
