Heels lead matches. Paige is already so gifted as an in-ring competitor that her being a babyface, from a sheer "traditions of pro wrestling" sense, is ridiculous. Ideally, you want Paige controlling the match, and giving the fans an entertaining ebb and flow of competition that someone seasoned in crowd psychology can provide. As a heel, I'd imagine that Paige versus say, Emma, Brie Bella and Bailey could especially be tremendous amounts of fun.
