I think the important part about Mick is the lack of ego. He will make your pretty boys look like the belong. He will make your monsters look monstrous. He will make your super heroes look like monster slayers.
If he wins, it will be like he won a god damned war, if he lost it will be like he lost a god damned war.
He is probably the most versatile promo ever to pick up the mic in terms of being able to get across both super serious and super silly and make you believe in them.
The person I would pluck from their prime and drop into modern WWE, but not in the ring, as the # 2 creative guy, would be Mike Quackenbush. I think more than anyone, his ideas combined with Vince's desire to be a TV show that happens to have wrestling, would result in actually getting that to work properly. long term long form story telling, building to natural peaks and valleys and escalations without getting to far into the Dog Food, a grounded comic book style WWE universe would be awesome
