Sorry, I haven’t read everyone’s post so I apologize if I duplicate. And I’m sorry if I hit a sentimental item.
1. Camera. There are small, light (5oz) digital cameras (23.74 – 5 = 18.74)
2. GPS (5oz). Use small GPS with good map (12.38 – 5 = 7.38)
3. Cup. Go with plastic (0.5oz). (3.84-0.5 = 3.34)
4. Pot. Get the Kmart grease kettle. It’s nice (9.63 – 3.5 = 6.13)
5. First Aid. Yep. Cut in half (9.1 / 2 = 4.55)
6. I admire your stove and fuel choice. It’s hard to get lighter than a 0.4oz stove. And the fuel is easy to carry.
Total saved = 40.14oz = 2.5lbs
Hopefully your pad has a decent R value.

Good luck on the trip!
