What other than clothing, and maybe a quilt/bag do you think adds weight?
I can make you a quilt that'll come within 1-2oz of a normal generously sized quilt. Worn clothing doesn't count toward base weight as normally described. Am I missing something? I use a large torso sized pack, and I can crush 5lbs if I want to.
Ditch the extra clothes, and if you're serious about skin-out weight, fit to size not to baggy, use 3/4L tights to hike in and discard the bulky overweight "hiking pants".
This is just a generalization, and a blunt one, not directed at you or meant to offend.
The real method to getting SUL is minimalism, not lighter "same stuff" you'd normally take.
So seriously, what items do you think separate you from being able to hit that weight vs the smaller guys?
edit: Just want to make it perfectly clear that I think the number based weight statuses are completely irrelevant and useless, but if you've got a goal for a reason, etc. etc.
