I think the biggest thing CLT will lose are it's flights to the Caribbean/South America/Central America. MIA is by far the best geographic hub within the continental US for those connections for people on the Eastern Seaboard (although I think SJU could be turned into an excellent hub for the Caribbean if an airline wanted to go that route)
