Except of course that now your magnesieum alloy components would never survive the violence of a launch. The sonic loads sustained by payloads alone means these things need to be tough. When it comes to space throw out your knowledge gained from the movies. This tank is designed to withstand temperature extremes, both hot and cold. Hydrazine tanks have survived re-entry before, and not just the shuttle ones. There's one sitting outside my office building.
