The only good attempt I remember was Oso2k's r6 fairing swap on an 05. Look it up on SBN if its was not re-posted here. He did a pretty good job with it but even then it seemed like it was so much effort and custom cutting & bracketing work for something that ends up looking a little weird. The custom fit will have its potential safety hazards because of clearance issues. I know some people had this with custom fit bellypans. So I think its just introducing a lot of pain in your life for no good reason. Can it be done? Of course. But you would probably go thru an annoying period of trial and error until you get it perfect. Its probably easiest to go streetfighter if you hate your fairing. Or get an R6 if you want the r6 fairing IMO.
