i suppose you could. Just remember the mesh Ron uses is really fine and if you tear it, well you'll end up with guests at your sleep over. The bivy does have a floor, but personally I prefer the bathtub floor of the zpacks Cuben ground sheet if there is a chance of heavy rain. Keeps my gear dry as well as keeping my sleep system dry.
I'm actually about to order a Zpacks Hexamid Solo this afternoon. Planning on using it on shorter "camping weekends" this spring and in the fall and then using it on my JMT Thru July of '14.
