I haven't seen/heard anyone try. I know the atachment points are different, and the other change were air intake locations. Perhaps worth a try though...
Clutching at straws really, need to get a replacement fairing for my 2KR, cant find an aftermarket one so was hoping a 3LN would fit.
If you have access to one (to take a look at) have a good comparison of the two fairings. It may be easy to modify...
