I've thought of that I'm not sure if anyone would go for it.
It could be accomplished by just setting troops on murderous so that wouldn't necessarily require a war. Although claims of cheating in these grand melees might be cause to start one.
It's something I've always wanted to do - get a few single duchy kingdoms in a small area, and have them just war each other symbolically. Or, you know, since I mentioned War of the Flowers... How !@#$ing epic would it be to get an Aztec-inspired society-religion (but updated to a more medieval mindset) that overlaps the tiny kingdoms? Symbolic wars, where captured nobles are executed to feed a god of renewal and blood.
