What would be really interesting to see is if they go back to the roots of the Captain Britain power with the Amulet of Right and the Sword of Might, and change the mythos just a bit. Give one to each of the Braddock twins and have them be two sides of the same coin. Brian as Captain Britain and Betsy as Lady Briton. They would represent the dichotomy between reason and violence, as well as mind and body (in terms of their powers).
