Although an interesting idea, I don't think it will ever come to that in terms of add-ons. For starters, it's way too big... it wouldn't be practical to wield a sword and defend with a shield if the room you were playing in was too small... besides, I don't think older Zelda fans would feel confortable with that kind of setup (I sure wouldn't...). As a concept, it would appeal mostly to younger gamers, thus increasing the role-play element of the game...
