I like your list, especially if you'll be hiking long days and not spending much time in camp. There are a few things I would change, but its mostly personal preference.
First, those turkey bags are a bit flimsy. I use a cuben (non-hybrid) pack, but I don't use the turkey bags anymore. Its a little hard to keep them together for a week or more. I do see you have re-inforced the bottom seam; maybe that will fix the weekness
Second, I would carry a light rain jacket, maybe a driducks, and a light cuben tarp like a trailstar for the 2 of you. You're likely to have some rainy nights. My wife and I would be much happier in that than separate poncho tarps. Plus, you'd only have one tarp to put up each night.
Third, if you are re-supplying from groceries along the trail, its nice to have a real pot to be able to cook that food in. You can also cook one larger meal for the 2 of you and eat from one pot. If you're sending all FBC meals, your current set up is fine.
Fourth, I don't see anything for hanging your food.
Have fun. I'm jealous.
Fifth, the driducks pants are not durable at all. I like the top, but the pants are hard to keep together. If you've been able to wear them – great – but they split on me the first use. If you take them, use care.
