I also think that you will be able to get most of the power with an aftermarket fuel controller, probably even more than a stock F800GS because those run pretty lean. Ignition timing won't make as much of a difference.

I've got both F800GS and F650GS throttle bodies here, will have to see what the difference really is when I find some time in the shop.
I for one is interested in that.......
