This will definitely have unintended consequences - once you know that your opponent cannot make the top move, you would start abusing it. It might be fun though - I am recently playing Fischer's chess on lichess.org and it is crazy - you beat a 2200+ player and lose against 945 the very next game. A lot of fun though.
