I finally found the set of non-leading-axle forks I was looking for. I was able to score a set of ’82 GS750EZ forks off Ebay for $100 shipped.
Comparing them to the GS650L forks, they have the same length from the tube caps to the front axle, and slip right into my triple clamps (important, because the steering stem has been machined to mate with the Bultaco frame). I think I should get a much more comfortable trail figure now. I will need to pick up a couple of axle spacers to match, but the 750 and 650 take the same axle, so I will be able to source them from Suzuki’s parts bin; nothing custom should be needed. I should also be able to make use of the GS750’s integral fork brace.
