I dont see Fencer setting up two versions of the same game. But either restricting the c2-c3 opening move or somehow adding something like a dice roll to see which color would start the game is an option. Similir to backgammon where the dice decide the color. It wouldn't prevent the c2-c3 opening but would cut down on people padding their ratings by only playing one color.
