The danger of tank collapse not withstanding, your idea should give some
'extra' vacuum. After all, don't they use vacuum storage in automobiles to
assist wiper motors (old cars) etc.?

Yes, and those vacuum storage vessels on later model GM cars are
molded in the shape of a sphere for maximum strength, and manifold
vacuum from an engine is partial.

If you start getting down into a fairly hard vacuum like that tank
car failure with condensed steam, the integrity of the vessel starts
being a serious issue. A sphere is the best shape for that job,
anything cylindrical or square is going to need serious internal
bracing to survive.
