So my modern version of the kit would be:
GI Poncho
Wool sweater or Crusier (pref something that could be un-buttoned or zipped)
Wool watchcap
BDU pants
Wool socks
Hiking Boots
Wetterlings Small Forest Axe
Belt Knife (ML Kephart or BRKT Aurora)
DMT Double Side Diafold sharpener (Fine/Coarse)
50' Paracord
sm Backpack
Maxpedition Bottle Carrier 12x8
Stainless 38oz Guyot
Olicamp Cup
Guyot MicroBites
Hankie
Firesteel LMF Army
12 10" zipties
10' Ducttape around small tube w/ hooks & needles
Spool of 25# test monofilament
First Aid Kit (mostly meds)
The modern bow I have trouble with.
I could go with a modern bow & arrow which would be effective but then again I could probably make something for large game if needed. 95% of hunting will be small game.
.22 rifle would be really nice but a but limiting due to ammo (then again lead bullets while heavy can be used for fishing weights etc.)
A slingshot on the other hand provides unlimited ammo but takes some skill to use.
So I'm up in the air about this.
A 10' or 12'castnet would be very handy in numerous applications. The weights are the main drawback, I think my 12' one weighs like 10# or so. If there was an easy way to improvise weights I'd be sure to pack one.
Otzi lacked any sleeping equipment, I'd want to pack a wool blanket and a 10x10 sil-ny tarp.
Again this opens a question of Fleece insulation properties vs wool. Wool is a great insulator but sucks when it's wet. It stinks, is heavy, and take forever to dry. Fleece drys pretty quick but does it retain it's insulation properties when wet & how does it compare to wool?
I'd consider a small (like boyscout or
crusader or
GI ) cookset too for more versatility
