It's an intreguing thought, really. Do they make it a 'mane seven' or do they 'swap out' an existing member because the original character has moved on to other things (I can't see them ever killing off a character).

I have to agree with amerBoi that events in Rainbow Rocks firmly opens up the prospect of a Sunset Shimmer joining the Mane Cast. The implication at the end of the movie is strongly that there is potentially a seventh Element of Harmony. However, in the end, the possible existence of a Seventh Element only requires that we encounter a personality with the same traits as reformed!Sunset. Trixie could do it, as could potentially any other antagonist who is now trying to find their way back to a better way of life.
