Your list is IMPRESSIVE! I don't see any glaring ommissions right off, but I have to ask--How much does this thing weigh? Just something to consider.

I definitely don't have all the answers, but I decided to split my BOB into His and Hers backpacks. They each weigh roughly 12-15lbs, though they're not nearly as extensive as yours. There is a fair amount of duplication, in case we were to be separated, but the contents of each have been tailored somewhat to fit our experience and physiques. So, for instance, my bag has a mag/flint firestarter, Bic and Lifeboat matches. Hers has a windproof/waterpoof lighter, Bic and Lifeboat matches.

One suggestion I could make would be to try to get everything but your little LED on AA batteries. Saves weight and allows you greater versatility.

Nice work!
