Format for 4v4 Crew Battle?

Thinking about setting up a casual 4v4 crew battle among two towns here in Arizona. We play together anyway, but I figure a 4v4 will stir everyone in the group to practice more. So what’s the best way to do this? The game played is Melty Blood Act Cadenza, by the way

I don’t know anything about how crew battles work for 2d fighters. Feel free to educate me…

each player plays each player from the other team, highest total wins = winner.

so it would be 16 matches, team with most wins is victorious
