Finn Balor being the trainer of Becky Lynch is an idea that WWE should be contemplating using in a manner similar to Matt Hardy and Lita. Extrapolate this one step further to Finn Balor's Demon having a female steampunk superheroine counterpart (similar to a babyface take on The Joker and Harley Quinn), and you're onto something. The Demon is a merchandise moneymaker. Being able to pair that with a female counterpart could be a huge merchandise bonanza. Balor and Lynch playing off of each other would certainly work too, and give WWE a fresh dynamic for storylines and presentation, too.
