A problem when you propose game rules for literary or 'artistic' reasons, is that the foundation doesn't come from gameplay.
If your idea is to have a unit challenge another unit to a duel, add another game level of play, where the battles can be fought out, and based on skill of players at the mini-game, one unit or another can win.
