@MrTubbyguts correct, and I am in favour of doing that. But I have one policy with my stories. It needs to make sense with the characters. If it goes against those character too much, the answer will be no. As for Anakin’s role, it is special, unless there is a twin for Anakin, then it will obviously change. So, I am not restricting anything, but I am just thinking on how these character would react in a way that would fit their character. That’s what I am saying, some things may or not happen because they react in certain ways. Automatic? No, not really, but my answers back are not rejections, it’s my question (perhaps a bit stern and rigid but just argue back!) on how it would fall out. But as I said, it needs to make sense. If it doesn’t, I have a hard time doing it.
Yes, fanfic is to change things around for fun, but a story requires a red line that makes sense. That’s what my concern is when I am writing. Perhaps I am missing info in your ideas, then perhaps clarify. Just take this into account.
