This is also a neat idea. Though I would imagine it to be burdensome.

Meh, when I'm on the field doing army stuff, I carry 2 canteens each holding about a quart, neither of which are particularly heavy or burdensome at all. So at any one time I'm carrying half a gallon, I imagine that would be enough to do some basic, emergency maneuvers, or like... make a water whip.

Edit: I think half a gallon is only something like 4 pounds
