Hmmm... Couldnt you do a very thin aluminum piece on the bottom kinda like a large plate (after reducing the center profile)? Or would that not help too much with the rigidity of it?
Maybe like a coin/coin and a half thick aluminum?
I know aluminium isnt that strong, but I would think a large one piece on the bottom of it all would help hold it together. There is another way I'm thinking of as well. But that would just take forever to do.
