I've always thought that a good fix for those double walled top would be to use a 1" hole saw at strategic locations on the inside/ceiling. Place a piece of 3/8" wooden dowel propped upright through the hole to straighten out the sag (you would of course have to trial and error the length to get the sag out to where it looked good). Then, squirt in some of that injectable foam that you get at Home Depot and elsewhere to finish. You would then of course have to patch the holes on the ceiling, but the should be an easy fix.
