The clues are in the original book themselves: Peter Pan is an incredibly complex character, and story. However, according to Robert Carlyle; OUaT is looking to cast a 13 year old boy, in the role. This, in and of itself, is a very ambitious undertaking. The character, of Peter Pan, has yet to be successfull adapted in live-action with a young boy.

Though, your theory makes it sound like Hook may in fact be OUaT's Peter Pan.
