The complications involved in uniformly placing 51 stars on the flag would make this scenario unsuitable. ; )
I was just talking about this the other day with one of my friends when the prospect of Puerto Rico statehood came up.My idea for the 51st state (whatever it will be )would be keep the original 50 stars on the flag but make the 51st star be formed by the 50 so in other words when you see the flag you would see one big star in the blue field but when you look closer you see 50 stars and the giant star would represent Puerto Rico and the 50 small stars would represent all the other states
