Well, you couldn't just create something called a hanger and then be done. That would involve some serious coding etc.
But what you could do is create a planet called "Hanger". In the Mission BBS on this planet, there would be missions where, when you accepted them, your ship would change to another ship. You could set it up, so that whenever you bought a ship somewhere else, it would enable the mission in your 'hanger' that would allow you to switch to your previous ship, and allow you to switch to the ship you just bought.
Hope that makes sense, if not, I could do a little plug that allows you to switch between to ships to show you how it would work.
