there's at least 5-7 states where you could pass it as a constitutional referendum. The only hang up is that we are baked in as representative governments on a state level due to agreements made to the federal government constitutionally when we joined the union. You'd have to find a way to make a representative system function like a delegate system, but not under the eyes of the law. It seems like a real moonshot, but where I'm at all it would take is the courts to approve the language and around 50,000 signatures to get it on the ballot. 50%+ of the vote and it's enacted.
