Evan, Looks like a lot of great specialized choices. Since you say there are a lot of items you need to buy I would caution against building a gear list of items that are not available. I dont think your tarp or bivy are available (both critical items). Also make sure you understand the limitations of the pro 90 quilt. This quilt states it has 1/2" loft, loft isnt everything, but 1/2" is still 1/2". Maybe some owners can speculate on temps, but I'll toss out 40 degrees min in the bivy+themawrap+warm hat.
If you are only going for warmer nights then I would drop the surplus gloves. Your combined glove weight is more then your pack. I'd also drop the sleeping socks. Warmer nights in a synthetic bag. I use the "next days" socks to sleep in...this way they are already on my feet and ready to hike...also means they have had a day to dry out. This all assumes you have extra hiking socks, which I dont see (-3 oz gloves, -1.5 oz for socks, possibly)
I own a virga jacket and wisp windshirt, but I dont find that I need both. If using my ponchtarp I take the wisp, if using a regular tarp I take the virga. I dont seem to have a big issue with the breathability of the virga, it works fine for me as a wind jacket. (-3 oz for wisp)
Gaitors, unless in snow I wouldnt take'm. If you are going to be in subfreezing temps then I'd take a beefier bag. (-4.5 oz)
I dont see a stove? Are you going to cook on a fire? This requires locations where campfires are permitted and it requires skill, easy if dry, much harder if it rains. I would at least add some esbit tabs. Use rocks to prop up the mug and put a tab underneath. Also the tab will work great as a firestarter.
Pad is 1.5 oz...this isnt much of a pad. Leaves are fine for warmer nights, but again this requires additional time and skill in locating sites with thick forest layers. Your pad also needs to be your frame for your pack. I'm concerned a 1.5 oz will not be enough structure for 15 lb pack (gear+food+water) especially if it is 8" wide (not sure how this will work).
I'd recommend dropping gloves, wisp, gators (saving 10.5 oz) and use this to add a lower rated bag and 3/8" trimmed closed cell pad (golite ultra 20 and GG thinlight trimmed to 40" adding 6-7 oz). You would actually come out several ounces lighter and be able to tackle much colder conditions and your pack should ride better.
Again you have an incredible list, but one that also requires some special skills and the time to emply them: packing a frameless, setting up a tarp, fire building, camp selection, etc.
Good luck, Jamie
