Would it be possible to make the save data of Deception able to "interact" with that of Deadly Alliance? I've heard of this done with the game "Super Smash Bros. Melee", where you have to get a trophy by having the saved data of "Pikmin" on your card.

Think about it; access to the DA characters, old-but-fun styles, or even as a method of unlocking current secret characters?

If this could be done, would you like to see it happen?

I would like it if they could do something creative with it, maybe allow access to some DA characters.
