My favorite next to skin layers by far are the First Lite Aerowool. They combine the odor reducing qualities of merino with a faster drying synthetic. I'd take a couple of the Wilikin uppers and Benmore boxers for a trip like that. I can get 10 days out of 2 pair without odor building up. In a wall tent camp though I'd likely wash them and dry them with the stove.
For socks my favorites are the Darn Tough of a thickness matched to the season. I would probably pack 3 pairs of them on your hunt and one would stay in my pack every day. If I started getting a hot spot or cold feet I'd swap them out during the day. 3 pairs lets you wash and dry a pair and still have a spare in the pack. In my Seek tipi I'll turn them inside out at night and hang them by the stovepipe, have dry warm socks by morning. I also like to throw in a pair of really heavy Thorlo wool socks to sleep in if weight isn't a big issue. I slept comfortably in 0 degree temps in my 20 degree bag last year with those socks, merino long underwear, and the First Lite Sawtooth on in my bag.
Further from my skin I might consider synthetics, but often use merino just because my merino layers have the fit I like best. I really like my First Lite Sawtooth or Chama over top of the Wilikin base layer. I love their hoods is a big reason why. I recently added a Sitka Core lightweight hoody that I like very well too for warmer hunts, it fits like the FL ones. I don't like the hood on the Sitka Core heavyweight hoody, it's designed to zip up to just under my nose and if I leave it zipped to my chin the "wings" it leaves flapping annoy me. I am still searching for the perfect warmer synthetic hoody. I read that FL might be bringing out a hooded Halstead fleece I might look at when they get their new stuff out.
For my legs I'd take Kuiu Peloton zip off long underwear but I wouldn't use them unless it got really cold. I'd also take my Kuiu Kenai zip off puffy pants for long glassing sessions. I'd rather not wear long underwear when hiking and use the Kenai zip off's when glassing if I could get away with it.
That time of year I'd probably take either my FL Ucompaghre vest for an insulating layer, especially if I didn't take my FL Sawtooth. I'd take some combination of the Ucompaghre vest, Kuiu Kenai hooded jacket, and Kifaru Lost Park Puffy. I would probably not take the Kifaru that early unless I was expecting lots of cold or wet. It is a very warm jacket.
Pants there are lots of good ones. I've had good luck with Sitka Ascents for earlier season and Kryptek Dalibor II pants for later. I'd probably take 2 pairs of the Dalibor II's on that hunt and plan on the warmer pants eliminating the need for long underwear.
Rain gear I don't know what to tell you. I have a FL SEAK and Kuiu Yukon pants but acquired them pretty recently and haven't had terrible weather when I've had them on. I think they would be overkill for a hunt like yours. I have pretty much used light raingear if I didn't expect rain like the Cabelas Space Rain or Marmot Precip stuff. It is not very durable if I have to walk in it. If I expected rain I'd step up to a MT50 bib or Helly Hennsen stuff. If you are very active in that you will sweat. I have holed up in a Sea to Summit poncho tarp and stayed dry too under a tree. That works well if you aren't moving while it's raining. I will be in the market for better lightweight rain gear in the next year.
I like a softshell jacket since I haven't found the perfect lightweight quiet rain jacket yet. My favorites are the Kryptek Dalibor II for colder/wetter conditions and the Sitka Mountain Jacket for just a light wind stopping layer. None of my base layers are particularly wind proof so I wear a softshell over them a lot. The Sitka Jetstream lite vest is a good one too over something like the FL chama for high activity warmer hunts. My favorite feature of the Dalibor II is the hood. I am a big fan of hoods as long as they fit like I want. The Dalibor II hood is a very good one and works excellent to stop wind and add warmth over the hood of the Core LW, Chama, or Sawtooth. I'd love to have a hooded Sitka Mountain jacket. I considered the Sitka Flash hoody but reviews say it's cut very short and lets wind in underneath, plus I have a long torso anyway. The Mountain jacket does not have that issue.
Extra stuff I'd take:
-Gaiters I like the Kennetrek ones best of those I've tried
-Sitka Ascent cap
-Sitka liner gloves and Gradient gloves
-Kuiu glassing mittens (I can glass much longer if my hands are toasty in these)
-FL merino baklava (this helps with a wind in the face)
-Turtle fur ear band in blaze orange (I like hoods instead of beanie hats, so I put this over my outer hood to meet orange requirement)
