I don't think you got my point: I think, with (essentially) a giant hinge down either side, despite how much stronger whatever alloy is going to be, the container may not be as structurally stable as the current design. The current design is built entirely for longevity and strength--this new one seems to eschew that to me. That's not saying it isn't a good idea though. There is definitely a scope for improvement on the current design, and this might be a good start.
