This is probably not a realistic option. You make a good point about a means to leave the EU having been negotiated but it seemed sadly to be so poor as to be unacceptable to both leave and remain people. This is interpreted by Remainers as signifying that we have no sensible option other than to remain, and by brexiteers as we have no other option than no deal. Both positions have their merits, but of course the 'deal' was not the issue of the referendum, and although it of course is worthy of debate, to reframe the debate as being dependent upon the nature of the deal is to deny the referendum result. One of the things I most admire in the remain lobby is their success post-referendum in re- framing a binary yes/no in/out question in conditional terms based upon a 'deal'.
