Have you checked into the Verholen bar risers ? They raise the bars 85mm (about 3.3") and may give you enough relief. Some model years need a longer brake line, others do not.
The GT probably has other changes that may be cost-prohibitive to add to the S. Another thing, the windscreen will likely need to be taller as well. The GT has an adjustable windscreen.
I added a SW-Motech rack and top case for my S.O. When she isn't on board, I remove the top case, leaving only the base plate (which acts somewhat like a spoiler).
