This would truly be a one of a kind mod. I would love to see it (and possibly do it if my fiance gets her own bike instead of riding with me), but i dont know if it would be feasible due to the plastics overall in the seat area are different. May have to ask at the parts counter or (shamed to say it) wait for someone to drop their '09 FZ6R and have the seat not damaged, although very unlikely....
Best of luck to you, post any info you get about this mod
