The Super Training stuff sounds like it'd be cool at first, but left in the dust quickly.
Playing minigames for EVs instead of mindless grinding sounds like a good idea, except you don't have to pay attention to mindless grinding.
Not so sure about minigames being the right route to take. After playing games like No More Heroes that integrate minigames into so much of the games as a means to progress and the DS remake of Final Fantasy IV that feature summon monsters that level up via minigame success, it would only feel like just another time waster. Slightly less malicious than just plain grinding but mind numbing at best.
