New theme for a Djinni story?

[LovesDancing]

I think I've come up with an original idea. Man finds a ring with a djinni trapped inside. (Okay, not original but wait for it) The djinni hasn't got an impossibly luscious body, in fact she doesn't have a body at all and can't create one to inhabit. She can't make this guy be impossible to resist because the djinni can't understand things like lust and love. Long term story he teaches her these things/helps her get a body, but short term he tells her to make it possible for him to switch to an exact copy of anyone in the world, living or dead. Not only be in a copy of their body, but with their memories, intellectual gifts, abilities. Story ideas, change to woman/women with great beauty (or very plain looking) and explore what it's like to be a woman, be a man who women lust after, be a woman/man who is submissive or dominant, etc. Lot of different stories can come of this, could be an interesting theme for other authors to create their own stories.
