If you can use a thin plywood backer, the thinner aluminum should work.
It may be easily damaged, but with care will keep the water out.
As others have suggested, canvas or vinyl material, if placed over a backer will do.
You can use it without a backer, but you're back to a tent.

Waiting for "someday" will leave you on your deathbed wondering why you didn't just rearrange your priorities and enjoy the time you had, instead of waiting for a "better" time to come along...
