I think that you could make a really good Munchkin variant of the SHL that would be fun to play. For example, you could have a class system made up of player types, equipment would work essentially the same, and your "monster" cards could be different players from the league. I think you would need some sort of theme though, like the SHL has been taken over by a zombie virus and you are fighting through zombie players to see who's going to be the best. Or you could make the theme be enforcers of the SHL, and you are fighting random hockey themed monsters for practice before you get a chance to drop the gloves in the big leagues. You could also mix in various elements for buffs or debuffs, like tampering penalty, missed update, or forum ban. It's a bit out there, but I think it can be done.
