There is a factory supermoto model, you can always look at that.
If you are going for the 17" rims, you'll probably want a smaller front fender and a smaller rear sprocket. Then if you want a true SM look, a larger diameter front brake rotor and a six piston brake caliper.
Or you could just fit dual sport style tyres on your enduro rims, say Pirelli MT60? These will carry you safely over gravel/dirt roads too.
