I hope, somebody else has a cool idea

but i have to disappoint you a bit: I've forgot a limititation, only one barbarian civ seems to be possible.
Why: I forgot, that there's a player limitation for teams of 2, and one player is already the normal barbarian player.
I can make other players a vassal of the barb team, and so i have a small reference, which civ i can block from the diplomacy screen, but that's not really enough, because espionage and war weariness can't be blocked like that.
I have to examine that a bit more (didn't have enough time today), so the finishing will take some days more
