I thought about that too, it would give you some (minimal) wind protection from one side or the other... I was thinking though that with the triangles cut loose, I could tie them on wherever I needed some extra protection. If that means tying them back on to where they came from, then that's an option as well.
With the hex shape, there are a lot of different configurations you can make with loose triangles... (i.e. tying them both on the windward side, end-caps, etc.) they wouldn't be completely wind-proof or rain proof, but it could help in a pinch.
