I am not sure if FHM can handle RPG elements but having abilities you unlock when you reach a TPE milestone would be pretty cool. Once you reach a certain amount of TPE you can choose an ability which would be your signature move. There could be an entire skill tree along with this so that as your player develops you can either specialize or be a generalist. Of course balancing would certainly be an issue but with time I am sure that could be sorted out. Another idea could be a set number of one use items each team gets. Then, during the season the GM or a designated player could activate them for a game. Maybe it gives all the players a 5% boost to a stat or an edge in the faceoff dot. Whatever the case you only get to use it once per season (or perhaps once per playoff series?). Again super un-balanced and could be abused as teams just focus down the "top" team by everyone coordinating to use their abilities against the top.
