I have gone through exactly this process on my 2013 R3R and am happy with the result. I am located in Victoria on the Mornington Peninsula if you would like to try the position.
I have replaced the R3R setup with the rails and pegs of a classic which moves the feet about 4 inches forward. You will need complete rails, pedals and master cylinder as none of the parts are interchangeable. In addition you will need to rework the brake line to fit the ABS setup (Not hard) and also manufacture a bracket to mount the rear brake switch. I have since fitted aftermarket foot boards as well.
