We have no idea how "kicking out" is even a thing that could happen. I think we also probably still have work to do in properly accepting Kharaya-do, simply because being tied to a fictional world/culture is a bigger jump than we've been comfortable with.
So I can honestly say that, as things stand, just about any fictive would cause a lot of discomfort. Which is something to work on. I don't really see how to narrow down to a particular character. I guess I can just see a lot of things that could put us off, even if we were generally comfortable with fictives.
