It could fit on the game cards, you'd need 13 or 14 game cards. They can only hold 128 mb, but nintendo says that they can hold more than that amount, even so, it would be up to 256 mb (my own guess on that number there), even still, you'd need 6-8 game cards for that. I wouldn't mind if they did that, see how they would put the touch screen in the world of VII.
