I note that all the traditional peoples have animals to do their work. But the Westerners haven't figured that out yet.
I note the Indian / Sri Lankan / guy-with-elephant has a long slit up his skirt. Whereas the Lapps don't and I belive kilts (being for cold weather) have quite an overlap and not so much cross ventilation.
Since we deal with hot working days and cool or cold nights, how about slits in the sides to increase ventilation during the day (while maintaining sun protections) then closing up a zipper or velcro or buttons at night? Maybe back the opening with pleated mesh so it does blow around too much. A sudden gust of wind could cause decency issues.
Even if it's not your usual style, remember that all of these wraps provide some protection and you could up your clo rating by wrapping yourself in your tarp, quilt, or groundcloth and still make progress down the trail. Who hasn't seen a few Boy Scout trips end that way?
As to your original Q: I'd consider it. Or maybe another route. I've heard bicycling-style tight shorts recommended (without the padding) to avoid chafing. And I can see that. And I've got these Jockey brand atlethic-style underwear in wicking fabric that are superlight, wicking, snug fitting and not too revealing because they're black. So I'm debating about those as summer UL hiking shorts. Two pair would let the other one be washed and dried each day.
