I guess the best fix I can think of is to Ignore the rule that you don't swap first player marker in a 2 player game.
Don't do this! Swapping the first player in a 2-player game, means that each player will get two turns in a row, which means that you can easely leave you areas unprotected when you are the second player, just to cover them up when you next is the first player.
There is a reason why you shouldn't swap first player in a two-player game. Many rules could be changed, but this is not one of them.
