Might that be an easy out? Put the change through Parliament, it fails, UK stays in the EU. Sound like a great and likely option to me.
It's sounding like the formation of a plot line to a new series of Game of Thrones to me. England's going to need to find someone to tame the wildlings North of the wall - to help stave off the invasion of white-walkers.
In hindsight, the UK referendum was an utter shambles. The post I linked to where the term "post-factual democracy" was used describes it perfectly. People voted to leave with no understanding of the consequences, that being just one example. I don't know what implications there could be as well to reignite the troubles in NI.
