I don't think I would enjoy that at all (although NuBSG was not a bad show).
How do you have a United Federation of Planets without aliens?
ýmy idea is to set star trek thousands of years in the feature:
earth colonies many world, then there were wars for the independence of the colonies, a space middle age, with lost of technology and knowledge. The eart will be discriminate for its past of oppression and submit to occupation by one or more of indipendent colonies.
I begin a serie here: the colonie/colonies which occupy earth allow to earth people to explore the space, but gradually, and finally with a long rage exploration ship. It'll be a rebbot of Star trek enterprise.
