So this is what I'm thinking:
Just for the hell of it, we get a 3v3 lobby, everyone in the lobby MUST be in party chat (and that is the only voice you can use.) Once the game gets going, you all sing while blasting each other out of the skies!
Just imagine the spectacle of 6 flare gun junkers in Raid of the Refinery all singing "Disco Inferno," or "Take On Me" while in a game of Desert Scrap...
