Would be interesting, but it would be extraordinarily hard to complete. Keep in mind, the longest completed timeline on the forum in terms of years is Benconstine's, and that to about ten months for him.
It's an ambitious idea...It would basically be rewriting the entire history of the United States. However, this wouldn't be a one month idea or like my old TLs. It would be in the form of a history book about the United States. It would probably take at least six months to reach modern day.
I probably wouldn't actually start it until sometime in June.
