Woah, that sounds really cool. xD

I have a Zelda RP going right now but it's sort of tapering off right now. I've never had good luck with them either to be honest. I do, however, have way too many original ideas than I have need for. (I really like that story book idea, sounds like a lot of fun.)

I have stories that are heavily based off of manga I've read. Like, Dreamer. Where a girl is transported into a different realm full of magic and she, unbeknownst to her, has one of the most powerful abilities, the power to enter people's dreams and speak to them as well as the abilities to bring dreams to life. (Loosely based off of Saver and Red River)

I also have stories that involve females dresses as boys to become Knights. (Heavily based off of Hana Kimi)

And a story that involves a magical doll that turns into whatever person the finder needs. It also has an alternate story where she never changes but simply stays with her 'master'. (Not a sexual RP in any way.)

I tend to stay away from fandom RPs unless there's a real element where OCs are plausible like this RP.
