How about Coroplast? It's light, it's stiff, it's cheap. It's not
particularly UV resistant, but covered with foam and fabric, that
shouldn't
be an issue.

For those unfamiliar with the material, Coroplast is like corrugated
cardboard made out of polypropylene. It's available in various
thicknesses.
You can pick up small pieces of it at sign shops.

Have you ever worked with the stuff??? It is as bad as aluminum for
slicing, and it has the distinct disadvantage of being inflexible.
Particularly the stuff used on greenhouses etc.

There is a family of RC airplanes that are made from this stuff. Fairly
easy to fabricate and pretty tough...

I've gotten paper cuts working with corrugated cardboard, too. Covered with
something, I think it would crush more easily than aluminum. Also, I was
thinking of the thinner 2 mm or 4mm stuff. Don't the greenhouses use 8 or
10 mm thicknesses?
If you slice along the corrugations occasionally, you can get an
approximation of a smooth curve.
On second thought, since you can form it using a heat gun, maybe it wouldn't
be such a hot (hah!) idea. It can get pretty hot in a closed cockpit. It
wouldn't be good if it sagged from the heat
