I'm also kinda curious, why you would want to do this. Not that I scoff, you understand! I made a new lever for a bokenSuntour barcon, and totally re-shaped the body in an effort to make it look less Japanese. I ended up with a shifter that works well enough (though not nearly as well as the original Suntour one) and (in my humble opinion) looks better. At least it suits the bike stylistically, which the original Suntour didn't.
