To be honest a 'Norway' brexit could not possibly have any appeal to Brexiters, how could it ? It means everything remains as before just with no voting rights. It would be a 'Brexit' which satisfies the referendum result, but nothing more than that ie. on paper only. However, this 'Norway' model may just buy Britain the time it needs, because it is not a final resting place - there is nothing officially stating how long a 'Norway' model would have to last, and so it could be used by both sides as a kind of halfway house preceding either a full hard Brexit or a return to full EU. status depending on how opinion develops in future. At any rate it wins Britain time.
