Personally, I'd let any of the red states go. Just about the only one that is cash-flow-positive (with respect to the federal budget) is Texas. And, it's not that I dislike TX, I just would be happy to see them successful on their own. If enough red states go with them (as a single country or not), it'll offset the federal budget. If even more red states go, then it'll do a great deal for the federal budget.
