I don't think there's too much redundancy though you do have quite a few knives/multitools. I'm with Jim, spread them around in case something happens to a bag. Fully kitted I have 2 fixed blade knives, 2 folding knives, a SAK and multipliers. But they're all spread around either on my person or in different bags. Same goes with the lights. I have 2 headlights and 2 flashlights generally. I carry one of each on my person and then one in my backpack and one in my shoulder bag.

Also (and I think a similar suggestion was brought forward) pick up an ultralight daypack. These packs generally crunch down to fit in a really small stuff sack, and can hold from 1000-1500 cubic inches (the one I use weighs 11 ounces empty). If you need to set up a basecamp with all your gear in a survival situation, a lightweight pack can really be handy if you need to make day trips to find water, food, wood, or signs of civilization.

I like the idea of coffee filters. I'm going to add some to my own kit!

Otherwise looks very complete and well thought out...great job!
