My foot layers are going to be thin liner socks, MYOG silnylon VBL, thick wool socks, removable boot liner, shell of boot, built in gaitor on shell pants. I haven't needed an extra gaitor in the past with these boots/pants combo. The thing I don't have is a pair of liner socks for each day. Will I destory them under VBL or will they soak through so much that they become useless. My plan was to take my day time wool socks, liner socks, and boot liners off and put them in the VBL sack with me each night? Will that not work? I guess I should probably have a back up pair of liner socks like my night time wool extra pair.
I have gone back and forth about VBL clothes vs the hot sac. I decided with to go with the hot sac becuase I am not sure how I am going to like VBL. I have never had to deal with it before. Only going on weekend winter tips with entirely synthetic insulation I had never heard of it until this spring. If I like it my next step will be to make probably exactly what you mentioned and be a happy dry camper. I think I see a ghost looking at your list. I feel more comfortable that I should be good for a week excursion in the snow with our layering similarities. One thing I noticed is you have a pair of insulated mittens. I have a pair that I could drop my shells and just take my liners for cooking and eating and then put the big mittens on for the rest of the trip. Would that be a better solution? My concern that I hadn't really thought of is that my hands at rest might get cold with just my latex, liners, and shells on. I might have more versatility with the latex, insulated mitten, and liners. There would be little weight penalty (3 oz I think).
