That's quite a comprehensive list to say the least!!
I would probably only make a few suggestions, but then each to their own
One more pot/pan - if your current one gets lost/damaged, it would be a pain to try and "make" another one
4 season sleeping bag - it's sods law that if the defecation did hit the fan, then it would be the first night where your region gets to experience temperatures well below a two season bag.
LED head-torch like mentioned earlier - could be especially useful in a "rescue" scenario, as if stuff is going wrong, people could need helping.
Final thing which I would put down as a big item you don't want to miss out - CASH. Bribes, trading, public transport, petrol, whatever - either way, split it into two piles (in case you get mugged) and bring as much as you can. If everything goes really bad, it will be useless, but then if that's the case we are really stuffed anyway!
Other than that, it certainly sounds like a good list!
