I'd definitely recommend dragonhaven for Chocolina! I play Lightning there (biased, yes), though I'm still only considering a canon update to LR, and we have Serah and Hope too. [EDIT] AND NOEL wow I'm awful we have an adorable Noel and I forgot him for a second. Since the Farron sisters run a boarding house of sorts there's a lot of available cross-canon CR right away, and the game world is huge with a variety of settings for Chocolina to get stuck into. She could easily set up a shop or a service with the help of the world's moogle population, for example, and chocobos are everywhere so she wouldn't seem out of place.
