This is a good list. But, it shows that you don't have a lot of experience with a systems approach to packing. Each system category is a component or subsystem of the pack system for 24 hours, assuming the worst weather/temps expected. This takes dual use of gear one step further.
Step one is to eliminate duplicates for function. (This is ignoring backups, if you want them. These can be added back, but we are talking minimizing weight of your EXISTING gear, pointing to where weight can be saved.)
Each sub-system in a pack needs to be analyzed for function. These functions can often be fulfilled based on cross sub-system uses of gear that is may not be related in function, but, close in fulfilling the parameters needed to satisfy a particular piece of gear. Example: using a long handled spoon as a stake.
Then you need to decide on independence. That is, you do not need an item while it is in use as another item. Using the “spoon” example, we quickly find that “sitting under a tarp in bad weather” and “cooking and eating” may cross. The decision whether to use it as a stake, OR, as a spoon can conflict, so, it is a poor example here. However, using a hiking staff as a tent pole doesn’t conflict. You can safely drop the tent pole. But this is more strictly dual purposing gear. A better example is a pads. You can use a pad for sleeping on, of course, but it has structure, too. You can use this as a pack frame. Either rolled up, or, in specially designed pad pockets. They do NOT conflict because you cannot do both “sleep” and “hike” at the same time, their use is independent. You can drop a 2 pound, internal framed pack for a 1.5pound pack (usually by removing the internal frame) and use a sleeping pad as a frame without ever noticing any difference. Follow?
Another example: Tooth paste. For three days, you don’t need tooth paste. You could substitute a drop of soap, but really, the use of tooth paste is simply to cover up the bad smell from partially decayed food. You don’t NEED it. (Some evidence suggests that the abrasive may actually harm your teeth by wearing away the enamel.) Another perhaps better example is a silverware set, which I did not see listed. Analyzing the nature of the spoon, fork and knife, we can instantly toss out the knife as a duplicate. A fork only facilitates grabbing food into your mouth as a spoon does. Of these, a spoon has greater utility, yet, pretty much does the same job as a fork. So, only the spoon is needed in the cook kit. If you bring sandwiches for three days, even the spoon, stove & fuel, can be dropped… but this is getting a little too impractical for my taste. I like my cup of coffee in the morning. I am sure you are catching my point.
I didn’t do a full analysis on your gear, but you should do it. I would suggest dropping “spare cloths” entirely, though. Clothing is generally not duplicated (except, socks, maybe underwear) for any time out less than a week. I would guess you would minimally enter the light weight category, for three days, just working on form & fuction of your gear.
