I doubt it. Politicians and voters will keep pointing the finger at Switzerland and Norway how they succeeded without the EU and that they can too.
I can't _really_ see people in the UK opting for a Norway type arrangement vs EU membership, though I suppose to some extent I suppose it does depend on how it's sold; per the Brexit referendum the public is not _that_ interested in the actual facts of the matter vs the marketing.
