I don't know how you'll keep it cold. The best I can think of is to bring a solar panel, high efficiency battery, and either a portable ice maker or a small fridge. Rig up a backpack so that it can charge (or run if its a fridge) while you hike, and you should be good. Maybe bring a small fuel cell or generator or something too, in case you spend too much time in the shade?
Thing is, though, all that stuff is gonna be HEAVY. and displace normal gear. Don't suppose you'll have a pack-mule or something?
