Oh man, those are most definitely Precure muses, and I see you're up for AU games... it might be a little fast for your needs, but I'll pitch anyway just in case. I play over at savetheearth, where characters are reincarnated from their past (canon) selves. They can regain their former self's memories, powers, and possessions (and fairies) as they go about their lives, and they can affect the plot readily. I've got a pretty big crate of castmates for you, too: Moonlight, Dark, Rhythm, Sunny, and Diamond. Over time, your power and item regains can very much return Cure forms to you, or fairies, or just about anything else. The AC is simple, at least.

This is kind of a short pitch, sorry; I'll be happy to answer questions if you have any, and if this isn't what you're looking for, that's cool too. Happy hunting either way!
