Buy the R80 and skip the conversion.
Touring on an Airhead is all about what you leave behind, not what you take with you, so a few personal items and a couple changes of clothes, a few spares and your Significant Other is all you need. For that, an R80 should be perfectly adequate.
Of course, if you're both (Ahem...) overweight and you like to carry a lot of crap with you, skip the Airheads entirely and buy a used K-Bike. A decent K100 won't even notice the extra weight and they have a rep for bulletproof reliability.
I've owned/ridden most iterations of the airheads and the R75's and R80's are some of the sweetest/smoothest and longest lasting engines that BMW built, despite the fact that I prefer the added torque of the R100 engines.
It's all a matter of taste!
Hate rots the pocket that carries it.
