I would pick up a second bike on ebay, overhaul and rebuild with other bits where necessary. Use http://www.competitivecyclist.com/za/CCY?PAGE=FIT_CALCULATOR_INTRO before you start bidding so that you can something close to the right fit and just have to make minor adjustments to eff top tube but shortening/ lengthening stem. I would strong recommend picking up a bike with a 73 degree head tube angle which I am finding unbelievably comfortable as it softens the ride way more than the harsh 74 degree I have been riding, for touring that is great. Most old Raleigh racing bikes seem to have nice geometry for touring .. by old I mean 50's / 60's .. in fact I have a 57cm top tupe/ 57cm seat tube 1961 Gran Sport frame with chromed fork ends spare which I was I was about to build up .. stem is currently stuck and removing the fixed cup in BB will be hard but otherwise its supposed to be a very nice frame as it was their top end tourer at the time (although strangely that year I think they built it out of non branded tubing) .. welcome to take a look at it
