Well you'd still have to get passed, possible extensions, votes of no confidence etc etc
Remember the person with the key to a No Deal doesn't want a No Deal, Theresa May is a Europhile, in fact her deal locks us to the EU rights wise more than the current one does, it gives them more leverage than they have now.
Honestly I can't see it happening, 3/4 of Parliament including May are opposed to it.
