It would be easier, and less disruptive of the inter-stellar continuum, and cheaper to boot, to sell this to somebody who want this feature (and they are out there, cowering in the shadows) and then take the proffered frn's and exchange them for a frameset without this feature. Otherwise, you would be upsetting the universal ratio of forks with dynamo mounts to those without, something not to be trifled with.
In other words dude, drop the dremel tool, take three steps back, .... Nobody wants any trouble here.
