Looks like you have it pretty well dialed in. Here's what's in my pack/on my person during MT archery season:
Attack pants
1/4 Zip merino top
Sitka soft shell vest
synthetic puffy
rain jacket
If I were you here's what I would do; ditch the rain pants since you have gators, lose the soft shell and use your rain jacket instead, ditch the merino bottoms (it got down to 16 last year and I never used merino bottoms). Unless you're in griz country, you can ditch the bear spray. Since you have your phone for entertainment you could lose the playbook too.
Do you have a puffy jacket? If you do throw that in as well and couple it with your rain jacket for wind/rain/snow, etc.
Do you have your Sawyer set up in-line with your bladder? If so, you could lose the other bladders and just roll with your 3L which would be more than plenty. I have an SG pack and put a 2L bladder in between the frame and the bag. Once it's empty it takes a couple minutes to remove the bladder, dip the bladder in a creek and place it back between the frame and bag. The bladder I have is a Cabela's brand where the whole top unzips so I can fill it in less than five seconds. My buddies are still pumping water while I've got a full water bladder put in my pack.
