So, that’s exactly what happened here in this alternate timeline!
While going undercovering, Chrysalis and Sombra strike a deal with pony, but instead of something that could help them with their evil plans, they end up adopting Scootaloo! At first they aren’t too happy about it, however, overtime, they start to warm up to the little filly.
So, Scootaloo has not only got a new mom and dad, but now she’s a princess! Lucky devil! XD!
Anyone wishes to do a fanfic on this, then by all means, go ahead! :)
