Having outfitted both my 2007 R3 Classic and 2010 1700 Thunderbird for "touring" it can be done...but.......I have found that since I have bought the 2014 Touring that it has the hard saddlebags, windshield, crash bars (front and rear), floorboards and running lights already with the sissy bar, pad and luggage rack already as part of the package. I think if you add up the cost of those items, labor to install them...you would probably be better off just going ahead and getting the Touring.
There are plenty of pictures of both of my previous "toured out" Triumphs in my photo album if you want an idea of what I am talking about.
I don't think the R3R would be as good a candidate for this because of the location of the pegs and lean forward position...but it is you money...do what makes you happy.
Just my two cents.
