You could always make it an optional feature in Dynasty Mode. Just like in NHL 09 when you start a new Franchise and you choose Fantasy Draft On/Off, how many games, etc. In this case, it would be a Dynasty-opening choice of "RPG Mode" (obviously just a theoretical title) On/Off. Off, everything goes as usual. On, the various features it would entail would be added. I think it'd be a neat touch.
