As far as how much trail is too much, it's interesting to look at a survey of bike geometry on Dave Mann's "The Bike Geometry Project." I think you'll find very few frames offerring more trail than 62 mm, but I don't know why.
I got a local framebuilder to build me a fork with high offset (low trail) for a very reasonable price. PM and I'll send you his info. Fork is nice, but it took a long time.
The less expensive way is of course to have a fork bent, if it can be bent to provide the end result you want. If it has been bent once, many builders may be reluctant to do it again in the opposite direction.
The much more expensive route would be a new fork. Unfortunately, some builders don’t do forks alone, and some don’t build forksat all, they buy them. If you can find someone to do it, expect a price of $300+.
