My impression is that they aren't so much "super powered forms" as they are amplified manifestations of the negative feelings and aspects of each of their personalities physically possessing them, so for these manifestations to take hold is a very bad thing to be avoided.

I don't think pony Twilight would ever become Midnight Sparkle since that was a manifestation that possessed human Twilight, who has never been a pony nor an Alicorn.
