Another concept might be the swap of their magical abilities or talents. It can lead to really unique storylines where characters have to adapt to new powers.

Characters who were friends might now have a different dynamic due to the swap, like becoming rivals or having a more mentor - mentee type of relationship.
Well, Spike and Big McIntosh are also characters that some fanfics like to swap. Spike is small and often in the background but has his own charm, while Big McIntosh is a large, strong and mostly silent character. Swapping them can lead to some really unexpected situations. For example, Spike in Big McIntosh's body would have to deal with the physical strength and the work on the farm. And Big McIntosh in Spike's body would have to navigate the more magical and often chaotic situations that Spike is used to.
