I've toyed around with the idea. Basically my idea would be that Germans, Getai, Gauls, Lusto, and Casse can optionally choose 2 vs 1(20K + 20K vs 40K) instead of 1 vs 1 other factions but I'm not sure how up to it everyone is. A barb win would count as 0.5 wins per each barb player and 1 loss on the other player.
If people are up for it, that would be the best way to do it.
I would idealy have to make all the restrictions even numbered (cav @ 4, heavies @ 2, Mercs @ 6).
