I think you are exactly right as thats the initial plan and then the people of Scotland then have the choice to ditch the "regal knobs" further down the line.
It does seem quite a practical policy and a more likely way to rid Scotland of "regal knobs" sooner rather than later as the sensible majority of the Scottish electorate will override the wee pockets of hate or elite priveledge that still exist in Scottish society and help dilute both their awful cultures still further which must make Scotland a happier, less divisive and therefore a better and more tolerant country.
Scottish society then moves on to a meritocracy with a head of state we actually elect just like any normal European country rather than this undercurrent of tugging the forelock.
Even for a party representing British Unionism there used to be a strong positive republican tinge to the Labour party in Scotland and Labour movement such as Willie Hamilton and Mick Mcgahey.
All that seems long gone swept away by such a strong monarchist as Blair and the huge pay offs now available in the House of Lords for Scottish Labour party retirees as Life peers.
Lord McConnell of GlenScorrodale (Wee Union Jack), Lord Watson of Invergowrie (Mike the Firestarter, twisted firestarter), Lord Brown of Ladyton (Des to his mates), Baroness Liddell of Coatdyke (Oor wee Helen), Baron Foulkes of Cummnock (George the Jambo pish slaverer), Baron Darling of Roulanish (Alistair the Red via Loretto) and many more besides understand exactly what Scottish Labour party MP's and MSP's need to do in order to keep themselves in the land of milk and honey and there sure ain't any sop to republicinism these days.
