A solution to NOT drill your track forks and have a normal front brake nonetheless

Difference being that star nuts weren't designed to have much load on them. They certainly weren't designed to resist braking force.
A wedge will be more able to take the tightening that this idea requires.

IMO.

Well, as said: it's not that important at the moment, as my final design will look the same in both cases and everyone then can choose on their own if they prefer starnut or expander/wedge.
