I was thinking if Bethesda ever decided to bring back the Enclave in the future. It should be a completely new Enclave, an enclave that wants to bring back all that was once good in America. An America with freedom of speech, an America where every man, ghoul and mutant would be treated equally. (Anyone remember how imposing Frank Horrigan was? Imagine thousands of them in enclave gear.) An America that is against slavery. This new Enclave could start to recruit from the local populace, much like the MWBOS. Offer protection in exchange for their most exceptional members of the tribes. This new Enclave would try to redeem itself and atone for the sins of the past.
I mean what's the point of restoring America or the world if you're going to repeat the same mistakes.
Also I'd imagine their would be conflict between the Enclave and NCR. NCR can just rule the western U.S and the Enclave could rule the eastern half. After all DC is in the east and yes I know the Enclave originated in the west. But that's NCR territory, this new Enclave wouldn't have the numbers to go up against the NCR. Not at present anyway.
So in closing they're should be an Enclave and Followers of the Apocalypse type of hybrid faction.
