I'd use spruce braces bonded with epoxy onto aluminum. Epoxy top to sides.
An 0.040" top with a shape would be stiff enough to withstand string tension with little or no bracing. English wheel would be used to shape about 1/4" transverse belly and fall-off to the end block.
Aluminum back and sides could be TIG fusion (or filler) welded but it would be a lot of work. I've built a couple cars with aluminum bodies.
