The big and obvious problem with any variation of this approach is always going to be "who gets to pick x", where x can be - The system used - The criteria for who gets a voice and who doesn't, and how much of a voice - What is called a 'representative sample' - Etc., etc., etc. There are only two systems that solve this problem. Democracy (partially), by effectively abdicating responsibility and saying there are no such criteria. And religion, where if the rules come from a universally accepted Higher Source, clearly that's who gets to pick x and will be accepted by anyone who accepts the Higher Source.
