I also considered building one out of spruce and balsa. I was thinking maybe making one much like alot of wings attach. By using two short dowls on the tail side of the pan, and maybe a nylon, or possible bolt and blind nut system on the landing gear end. I also considered making 6 little 1/2" by 1/2" squares out of 1/8" Ply with a 4-40 blind nut in each little square. Then epoxing 3 down each side, and using 4-40 bolts instead of the screws. Then I would feel comfortable just taking the pan on and off with my cordless drill. I would be afraid to use my cordless with the method I am using now, which is just screws screwed into the fuse side.
