So this one is entirely fictional, but since I know you said you were (at one point) running out of teams I thought I’d go ahead and suggest it.
Norfolk Yankees.
In Billy Joel’s “Miami 2017” he includes the line “They sent a carrier out from Norfolk and picked the Yankees up for free.” I thought that might be a fun concept, the Norfolk Yankees. The song was written around the time that NYC was going bankrupt, so the song was a “what if” about that.
