Here's another rendition of the Red + Blue = Purple idea...

Alliances stay the same throughout the match (I personally think it would be hard to change partners during the actual match, especially with strategy, but who knows). However, if lets say there are 2 scoring "zones" for you to place whatever objects give you points, and mid-way through the match, the zones "swap". So, whatever objects you put in yours, you have to pull out and put in the other zone and the opposite alliance vice versa. Thus, forcing both teams to be defensive, offensive, and fast... plus very much alliance cooperation to accomplish the task. So, no scoring zone truly belongs to any alliance. Heck, maybe they don't even tell you which scoring zone is yours till the match is going. Just an interesting twist I figured I'd throw in.
