Besides Queens County staying intact, Westchester County becomes a sixth borough from the start. This takes NYC to the border of Connecticut. And if there are not already too many wealthy people in the Hamptons to prevent this, make Suffolk a seventh borough on the grounds that Suffolk is too isolated from the rest of New York State by NYC for the state to adequately provide services to unincorporated parts of Suffolk. This will open up chances for such things as a potential bridge to Plum Island, Fisher's Island and Rhode Island.
