Yeah, this would probably be how it would work out… until and unless Fluttershy heard about Elmira doing this sort of thing to an animal. Then The Stare would come out, and I don’t think Elmira is genuinely evil(more oblivious)/strong willed, and definitely not magical enough to tank it like Discord did (whichever combination of those explanations one prefers for how he did that).
Edited
Would be like Pinkie x Deadpool.
