You're not going to get close to SUL with that paradigm. SUL stuff is perfectly usable gear, but it isn't bombproof. It stands to reason that the thinner fabrics are going to need a little MORE caution and will rip easier than heavier options. If you don't get most the items in your kit down to lighter options, you might get to a "light" stage, but not to a 12-14 pound UL base weight, or a 5-8 pound SUL base weight (my figures are my arbitrary estimates).
It's your hike, but don't kit yourself about getting a UL kit and doing things like hauling a heavy duty 2-3 liter bladder AND a stainless steel water bottle. Taking a tough MSR Dromedary 2 liter bladder at 6.3oz and a 40oz Klean Kanteen at 9.4 oz, you have added 15.7 ounces to your kit. A 2 liter Platypus is 1oz. The difference represents 18% of a 5 pound SUL kit or 9.5% of a 14 pound kit! Read up in the gear list forums and throw your own list up for critique. Expect brutal frankness :)
Use recycled drinking water bottles for a SUL, sustainable and cheap method of hauling water. Platypus bladders will last a long time and there's no need to fold them. If I'm using 1 liter bladders, they are riding in the outside pockets of my pack and I hang them in my laundry room with a clothespin to dry. I store them flat when dry. A Platy will last several years, but I think expecting a 10 year working life for an active hiker isn't realistic.
Items like knives and titanium pots will last a long time, but some things just wear out. Your shoes and clothing will be subjected to dirt, sweat, bug repellent, sharp branches, etc. Tent floors get ground into the dirt and rocks. Some things can be repaired, DWR coatings can be replaced, etc. Even "bombproof" stuff gets broken and worn.
Ultimately, light options will arrive and some of your gear will get rotated out for higher performance items. That should be done responsibly and sustainably, just like we (should) do with cars, electronics and other technical gear.
