I'm a bit iffy about it as well, however "To, by vote of the Consensus, abolish the Consensus" really strikes a good cord with me as even if I am very cautious of the "to a single sovereign" at least it would be by vote of the Consensus. It'd be non-violent and in-hand with the law. Personally, I doubt the Consensus would even think of voting for anyone other than an individual of "unimpeachable character". Much less even consider voting for the idea at all.
