I wonder if setting ply on top of walls and then spars on top of that is even better.

After seeing halfdome's pictures, I wonder if setting ply on top of walls and then spars on top of that is even better. And then I'm thinking I have a lot of narrow t&g cedar, and wouldn't that make an interesting ceiling. Laminate foam, ply, and final roofing on top of that. But please, dissuade me if you think I'm off base.

I need to pull out my grad school structures class notes and see if I can make the stressed skin roof panel work with 1x on the flat. Albeit, loss of insulation. I'm leaning toward 1/4" ply. I'm not even sure if there are published engineering data for 1/8" ply.
