I want to bring this thread back because it was a good one.
EC: I could see your idea working in a RTS better than I can in a racer. One person would be responsible for the actually fighting, while the other would be responsible for repair and defense. The both of you would be involved in the overall strategy.
In a game like that, you could have the two people responsible for repair and defense fight each other through their partners. For example, you could equip your teammate with a devastating bomb that allows no repairs for a few minutes, but of course it has to land. You could also control espionage members who sabotage or gain intel, allowing you to disrupt repair or quickly repair your own crew/defenses. All the while, your teammate is duking it out, trying to destroy the other teams army/fleet/armada.
Doing the repairs would require resource allocation and research with the most devastating attacks requiring a full control over your defenses; maybe maneuvering them, or fortifying them and taking control of the guns.

I thought of an idea that would use a peripheral, a series of blocks. These blocks could be stacked in any arrangement. They would be different colors as well to allow for different attributes.
How it would work. Well on the screen you have a character trying to get some where. On your Gamepad, you have your camera. On the table, you have your blocks.
You see your character and the end goal. You take your blocks and build them in the correct formation, utilizing the different colors which allow for different attributes, and then observe it with your Gamepad camera, digitizing them.
Your character is always moving like Lemmings. So if you fail, he/she/it dies.
It would be hard to make it work, but it could bring the family together.
