I see a few things that might be worth a second look. I do most of my hiking in TN/NC/GA, and SW-VA.
I might be concerned that the bivy would be too hot on hot and humid summer nights. Obviously you don’t have to sleep in it unless it is raining, but then you don’t have any protection from bugs, so you might consider something like a MLD Serenity Shelter or Alpinlite Bug Tent.
I would be surprised if the Ti spoon really weighs that much but if it does you can get a lot of Ti, Polycarbonate, or Lexan spoons that weigh under 0.4oz.
That seems like a lot for a bear bag and line. You might look at the 0.85oz Z-packs Blast Food Bag and get 50 feet of Zing-It arborist throw line (mine weighs 1.05oz in a small stuff sack). That would cut your bear bag weight by two-thirds.
5 liters of water storage is a lot. I never use more than two one liter bottles, so you might be able to shave a little weight there.
You could probably get that FAK down to two or three ounces pretty easy.
I don’t use baking soda for toothpaste, so I am not sure how much you use, but you might be able to repackage and save a little weight, or maybe not.
CVS Pharmacy sells a travel toothbrush that weighs 0.5oz. It’s the kind that comes apart and the brush slides into the handle.
Repackage the Deet and Purell into mini dropper bottles. That should make them about 0.55oz each.
You might replace that knife with something lighter like the Gerber UL LST or Spyderco Ladybug, They both weigh 0.6oz.
A mini bic is only 0.4oz.
Are you using the Marmot Windshirt as raingear and insulation? Aside from the fact that I am sure that you realize that the Windshirt isn’t waterproof, if it is the Driclime, which I am assuming it is for the weight, I would think that the lining would take forever to dry out once it got wet. I think you might be better served with two garments here. I suggest either:
A.) A regular windshirt (Montaine Smock, etc.) and a light puffy jacket (Montbell Thermawrap, UL Down Jacket, etc)
B.) A Dri-Ducks Rain jacket and a light puffy jacket
C.) A poncho tarp or cape (SMD Gatewood Cape, Golite Poncho Tarp, etc) and a light puffy jacket. (This also can replace your MLD Monk Tarp)
