It seemed like a great idea and I planned a whole series of ESB bounty hunter dreidels. While I waited for the molds of the other bounty hunters' heads to get fired, I made a prototype with IG-88.
I'm not entirely happy with it because it was marred during the glazing process. The glazed part of the clay can't touch the kiln shelf, so it has to be propped up on some metal spikes and they damaged the piece on the shin side when I removed them.
Also, it doesn't really spin very well and will probably break if I continue to test it.
