I would actually prefer that if there is going to be a Statesman in COH it is because somebody else picked up the Mantle and made it their own. How many Captain Marvels, Green Lanterns, Captain Americas, Spidermans, Robins, etc. have we had so far? That would give it a fresh start without any baggage and not spoil the existing lore. He could be a relative if it worked for the story and could have entirely different powers since "Statesman" doesn't really define his abilities like say, "Fire Dude" would. This would expand where they could go moving forward and allow many more creative opportunities.
