I really want them to do that, make a movie where Tink meets Peter, i mean. but i dont know, it sounds like it can be a tad dark, because:
1. why did she leave Pixie Hollow? 2. Why is she so grumpy? 3. How does she fall in love with Peter? 4. Does she ever visit Pixie Hollow? From what i can see, a great tragedy befell Pixie Hollow, and Tink lost all her friends, but comforted by Peter (which made her fall in love), and the Pixie Hollow tree became a tree for Lost Boys. and because she lost her friends and her house, she became extremely grumpy. But then that wouldnt make sense since Earth needs fairies to change seasons and keep everything in order. so maybe: Tink did something terrible and affected all her friends, so she was kicked out of Pixie Hollow. she felt betrayed and became grumpy, but then met Peter. and nothing happens to Pixie Hollow.
the problem is: what could be the crime that motive the tinkerbell's expulsion from pixie hollow? zarina is the only exiled fairy that we see, and i not belive that the producers of the films allow show tinker bell comitte a serious offense to their friends.
