Rodriguez had someone contract build them bunches of 55mm rake forks (1&⅛) for their disc braked bikes. You might give them a call. Maybe they have one on the shelf.

55mm is not 60mm, but it'd get you closer than you are. They are aluminum, smooth, disc. Nothing retro or lugged about 'em.
They also do custom to whatever your specs are.
Mine is 55mm rake for a 26 inch (559) wheel for a 69 degree head tube angle. ~55 to 62mm of trail depending on tire.
