I think this may be an option on earlier years but it looks a bit more difficult on the 2016. There isn't really a "little nub", its actually a solid casting all the way around with 2 little notches where the ends of the brake line go through. It would take some serious grinding to make much more room.

I may take the advice of mrhammer2u and go the custom route from magnumshielding.com.

 

that means you have two options if you dremel the nub. if you go custom, you'll still be dealing with the same issue. another option is to put enough distance in between the banjo hole and the banjo fitting to clear the boss.
