...I haven't heard of anyone trying it.
Make a spring to take out that long creeping travel. I use .030 spring wire. I've even used a bobby pin I found on the floor.
I've done it to six Slavia 634s. You will have to tweak the bend in the spring wire and adjust the spring behind the trigger to get exactly what you want. I have a crisp single stage trigger that I prefer to the ones in my HW 85s.
