I would say a bottle of Polar Pure or something similar instead of bleach. Biggest item I see missing is a SAK\Multitool. Maybe you always have this on your person? I carry a medium size SAK on me and a full size muti in my bag.
I'm still working on mine, but currently I carry:
Small FAK
LMF firesteel
SAK Swisstool.
Polar Pure.
Cheap little headlamp.
Fenix E20.
2 extra AA batteries.
A little external charger for my iphone that takes AA's.
Bottle of dryer lint.
Pocket tube of vaseline meant to be for lip use, but it's just regualr PJ in a tube.
Really small tape measurer, comes in very handy.
Really small vice grips, like 2.5 inches long, also very handy.
A small screwdriver. Looks like a pen, but has four mini screwdrivers in it for electronics, watches, ect...
A mini-bic lighter.
Ink pen.
Sharpie.
Two needles and some really strong "outdoor" thread.
Anti-bacterial wipes.
A small plastic scraper that takes regular razor blades, of course with a blade in it.
A really small retractable box cutter, one of the ones with the snap off blade.
Lightweight work gloves
Nitrile gloves (you never know)
Some duct tape of course.
Some of those small velco straps meant for holding AV cables together.
Two small carabiners and one large nite ize S carabiner
Medium fixed blade - I change this up between different knives.
Large folder in addition to the fixed blade - probably overkill since I carry at least a 3" folder in my pocket at all times. The one in my bag is a more of a beater though.
2 Pure Protein bars.
I don't currently have, but plan to add soon:
A couple of N95 mask if I can get them packed down small enough.
A small bottle of gorilla glue, I just need to figure out a bottle to use, the bottle I have is to big. Maybe a Visine bottle or ?
An Orange Bandanna
A slingshot band - just the band.
From your list I need to add some tick tweezers (good idea) and some drink mix. I would consider the drink mix more for water that doesn't taste so great, not really for energy, so maybe just a kool aid pack or something. I might also add a few of those energy gels since, as someone pointed out in the clif bar thread, it does take allot of fluids to get those bars down.
I also don't carry that much 550 cord. It's too bulky for my bag. Instead I carry 50', then carry another 100' of cheaper lighter weight cord. 550 is usually overkill for what you end up using it for in my experience.
I have all of this in a maxped neatfreak, once I add the other items it's definitely going to be packed to the hilt, but the Jumbo is way bigger then the neatfreak. Mine is for EDC and I stick the whole thing in my pack when I go hiking.
Edit to Add: I have several W&SS threads to thank for many of the items in my bag
