That sounds like a pretty cool idea, although I personally destroyed the Brotherhood in FO4, I preferred Elder Lyons' idea of what they should be so I'd be curious as to how they incorporate that into the game for people who didn't side with them. It'd be the only way that I'd care to see the Enclave again. I mentioned New York City being the setting of a dlc or even game in a different discussion which I think would be pretty cool as well.
