Even so, I hardly see that being an enticing olive branch for the disillusioned Scottish electorate. A symbolic relocation of a pointlessly ceremonial and archaic relic of Westminster politics to their doorstep isn't going to be the buffer the Tories are hoping for.
The reality is, short of dramatic Brexit u-turn, I don't see anything slowing down the tide of nationalist sentiment in Scotland over the coming years. The best chance Boris has IMO is to call Sturgeon's bluff and offer them an early second Indy vote, especially since the Scots are still at an impasse, possibly erring towards staying in the union. That's obviously a huge risk, but if he's triumphant then he'll have a renewed mandate of conclusively nipping the debate in the bud for another generation.
