You can bend your own fork. There are a number of people that have made fork bending jigs, and lots of photos on the web.



Just keep in mind that the "straight" forks are actually raked at the crown. You will have to be judicious if you add more rake.

I think I'd only do it on tapered fork legs. MTB fork lags that are round, and the same diameter the length could be interesting to work with.
