You're going to paint it? Why not heavy paper or light weight cardboard?

That would work (I think it's basically what paint-grade edgebanding
is), but where can I get a single strip 200 inches long?

I wanted to have one seam (on the back side) rather than three
distributed around the perimeter. I don't know how I'd bend Luan

How tight a bends would you need? 1/4" Luan bends pretty well. That's why
they use it for backyard boat building. Make sure your scarfs are in the
straighter sections just to be safe. Epoxy your scarf joints.
