Bending forks used to happen all the time. (And every steel fork out there is bent by the builder. Well, OK, a few of the recent ones are straight, set into fork crowns that are raked forward.) In the old days, every bike shop and the tools for bending pipe. Nobody thought twice about adjusting the rake.

That said - why do you want to take an inch of rake out? Do you want a ride so stable that you can ride no-hands while being bumped by a truck? You ADD rake for quicken steering for a sportier ride and SUBTRACT rake for more stable steering. Also, much if the "sweetness" of a frame is in the steering geometry. If you like the ride of the bike, think long and hard about messing with front end.
