I can see how you could make an argument that it would balance the game, but it's already completely ineffective against one of the most common offensive types in the game. It's strong against Flying, which is useful but Flying already is a shit defensive typing to Electric doesn't have a monopoly. Then theres water, which is super common, and is Electric's main strength, along with it's typical Speed.
I think it's pretty balanced either way. it has a niche, Fairy being super-effective might overpower the type.
