I think that's a very coherent strategy. It's already been laid out more or less how it would work: defeat this deal, get rid of May, get an general election, win the general election, get rid of brexit, with a second ref or something.
There is a certain incoherence to many of the whines from keen brexit types over holding a second referendum. If you're after some kind of 'hard' brexit, surely you should be all for it. A clear plan for what brexit will mean is presented with the promise to implement it or something similar with a second leave vote, tying the country to your vision if you win. So the only reason they can have for not wanting a second referendum must be because they think they would lose it. Why this new referendum would somehow be an affront to democracy, while the 2016 one was more or less the last word on democracy, I've yet to hear explained.
