I think one of the better games that could have an SHL edition would be Munchkin. Munchkin already has way too many expansions so an SHL version would fit right into the current bloated mess. Now the biggest thing with Munchkin would be coming up with fun cards as equipment/bosses/events to represent the broad community of the SHL. I think there is enough history over 50 seasons to come up with some good stuff that everyone will enjoy.

Some examples include

The Augment: +3 Armor - You are now a robot capable of outlasting the competition.

Penknight Radio Broadcast: A horrible sound emits from the radio, choose one opponent to discard their current weapons.

Skates of CC2: Some say the best there ever was wore these. +1 to any side you play it on

You could easily have all SHL teams substitute for Class and have their SMJHL Team's substitute for Race in the game to add some extra flavor.
