Does a UN Variant exist?

Because what i thought of was for example that in Winter all players can vote to sanction a Country which in the next year isn't allowed to attack or support. This would lead to some interesting dynamics were mostly the most aggresive player would get punished. Plus you could even make the vote anonymously to add a twist. Does something similar already exist?

Edit: Or you could let the players elect the "Secretary General" who could then sanction a player. Or you could designate a "Buffer Zone" where Movements aren't allowed for a year, etc. etc.
