Judging from your analogy, it seems to me it might work, even in a
drought. I often wear a surgical mask when I'm on a long airplane
flight. I don't do it for the germs, I do it because the mask is an
excellent "antitranspirant". As I exhale, a lot of moisture I
breathe out is trapped in the mask, and when I breathe in, the fresh
air picks up that moisture. Since I started wearing a mask I stopped
having to drink lots of water on airplanes, I stopped getting sore
throats, and I get much less "jet lag". It turns out that the
symptoms I thought were jet lag were largely dehydration.
If a face mask can trap water without interfering with breathing (at
least, not enough to matter) it seems plausible that a waxy leaf
coating could do so, too.
