Nice veneer glues which are worth it because they don't leak through the thin veneers. So I vacuum veneer the back and then do the sides with multiple wraps of inner tube strips. Last I cut the binding ledges after applying a thin shellac layer to strengthen the veneer edges and prevent blow-outs. It is possible that you could veneer the back with lots of inner tube but the vacuum process is pretty easy. I have done this with several Saga mahogany resonators to upgrade them with walnut or maple. Good luck!
I was wondering if laying something soft and heavy like a bag of sand or rice over the back might work to clamp it?
I would first soak the veneer in water till pliable. and lay it back down on a couple layers of close-celled foam pads that they sell for backpacking. Stack the inside with sandbags, barbell discs or some other heavy material. Use enough weight to press the veneer sandwich into the foam padding. Let it dry overnight, and the next day it should have taken the correct curve. Apply glue and stack it up again till the glue sets.
If you preferred to eliminate the weights, you could cut a disc out of 3/4" plywood and add it to the bottom of the sandwich. Then you could clamp it all the way around with C clamps.
I think this would work for the typical 1/32" or less veneer thickness. I doubt if it would work with veneer as thick as 1/16".
