I really like the idea of making your winter PSK around the pot - kudos to you
In winter, your primary PSK is your clothing - both on your person and the extra layer in your pack. Then hydration, then calories. (Yes, you can survive without food - but you'll freeze to death or permanent damage much quicker when hungry). So remember that what you're wearing and what's in your pack (besides your PSK) will be more important than the actual PSK.
I'd ditch the cigars and some of the cotton for the AMK bivy bag ($20 or so?). Or at the very least a heavy duty thrash bag.
Put the vaseline and cotton balls in the freezer for an hour. Take it out and try to make vaseline cotton balls. Tell us how it works (don't ask me, never tried making any in less than room temperature - but I would be surprised if the cotton would wick vaseline at low temperatures).
Personally - even if the above experiment turns out in your favor - I'd pre-make the vaseline-cotton tinder balls and leave the jar at home. That should leave room for some calorie rich snacks.
Unless you like to hike holding that pot in your hand, your kit doesn't need to be limited to your pot. That pot goes into something - a bag? A stuff sack? A day pack? If you can't fit the bivy bag/thrash bag IN the pot you can wrap it AROUND the pot before stuffing it into whatever you're using.
One thing you might consider adding is an "Original Buff". If you haven't seen one, it's a lightweight, compact-folding tube of microfiber fabric you can wear as a neck gator, headband, beanie, pirate's cap, face mask or balaclava. They're available in sport goods stores (I got mine at REI).
I got one last summer because they are great at wicking-away sweat (I sweat a lot). Then I saw a few people snow boarding with them on and decided to try it out myself.
I use a wool buff. Cotton is great for wicking away excess moisture and breathing, so great when your moving about. Not so great for keeping you warm when you're not sweating, but freezing.
