Remodeling Superstars

I can think of 3 instances in which Superstars have been remodeled (Del Rio into Rezar and the other being Enzo into Akam, who eventually turned into Showboat Kofi). Why can't we continue the trend with people who have gone to other promotions and have been phased out of the game. There's no chance of them showing up in loot grabs, thus eliminating some important trainers, links, etc. As a bonus for those who might have the original Superstars, let those be "gear" and give a slight bonus of that person's training/coaching ability.
