very creative
I like the Miami Sharks, from one of my favorite movies. Speaking of movies, I can't wait for the new De niro movie (Vince Lombardi biography) !
ANyway, I think fantasy teams 's got a great potential. I believe perhaps you should take a look on fantasy miniatures : now most of the products are plastic or resin made, light enough for miniature football. (see attached examples).
We could imagine special rules to manage the very big figures (ogres, trolls, etc...) and even magic events (same system some of you use for "special events" like injuries and fumbles, for example).
We also could imagine athletes death ! Imagine a team of Chaotic barbarians, powerfull but not skilled...put them in front of a very fast Elven team, and then lets them smash their faces....if a team is completly wrecked, end of the game
I 'm sure we could use a similar system used in fantasy board game "blood bowl", but with the dynamic action of electric football.
