Critique My Gear - Winter Photography

Hi all. I would appreciate your opinion on my gear list. I am going on a winter photography trip along the Overland Track and side trips, over 11 days. This means lots of gear and food and unfortunately lots of weight. Currently my total weight is around 30kg and I have been training with 42kg doing soft sand and stairs. I'm 80kg and have done the Overland in winter before.
I've got 640g of food a day which gives me about 9300kJ. I will need to boil 13.2L of water for all my dehydrate food and coffee. I have tested a 100g gas cylinder to give me 8.5L of boiled water. So I will take 3 to cover the requirements and give me a bit of contingency.

ID:
Pencil and notebook are for a diary.
Electronics:
I have two power banks. One will be attached to the phone at all times. I am using the phone to record GPS tracks and also at night for entertainment. The battery is very weak and it will not survive long in the cold, hence why I have to attached to a power pack at all times. The other power pack will be used to charge the camera and headtorch batteries. This power pack will be charged using a solar panel. I have considered using a larger power bank instead of the solar panel but it comes in as the same weight and at least with the solar panel I can get more charge (assuming I get clear skies).
Clothes:
I will be sitting around in the early morning waiting for the magic hour light to photograph so I want to have enough warmth. I have 4 pairs of liner socks, 3 of medium socks, 3 underwear. Glove system is liner gloves and over-mitts. This is so I can have warm hands and also have some protection when I'm using the camera. I also have a pair of medium gloves that I was going to use when I'm using the camera, but I will probably remove them.
Water filter:
Not sure if i need the syringe to back-flush. I haven't used this filter in the field so not sure if it will survive 35L of filtering without backflush. I presume I will be using the tanks at the huts mainly.
Packaging:
I haven't finished sorting this out but presume it will be about 500g.
Winter Tools:
Last time I went I had to bail on climbing Cradle Mt as the boulders were covered in a dusting of snow and the risk of slipping and cracking a leg was too high. This time I want to be more well equiped so that I can get on top and get the shot.
Bedding:
Could probably lose the liner. I read the new rules about having an at least -10C sleeping bag, bun not sure how strongly they enforce it.
Photography:
Could possibly lose the 3rd lens. Everything else is required. Please don't suggest I leave the DSLR at home and just use my phone.
Camping:
Flint and steel in case piezo dies.
Towels so I can clean my kitchen supplies and not have water inside my pack and the dirty one is to clean the bottom of my booties so I can wear them around the huts and also inside my sleeping bag.
Should I bring thongs to use around camp too?
I prefer a bladder so I can sip on the go.
Daypack needs to be able to carry all the camera gear, tripod, water, food, emergency supplies.
I have a lighter main bag but I had to get a new one that will carry 30kg and 90L comfortably.
Thanks for your insight.
