Yep one of favorite artists, Chaoscroc, does lots of fan art of roboticization, using much more detailed mecha desgines that the show did.

One idea he had but never really completed was Princess Sally being put in the machine but their is an error, so instead of a robot slave, the result is a Free Willed Evil Robo Sally.
