I had this idea about creating a rocket that once it reaches orbit you can rotate the ship 180 degrees and decouple a covering to a engine that used to be at the front. That would make it so it would be more aerodynamic from surface to orbit but turning it around to reveal a heat-shield that would allow you to actually fly down on re-entry. It may sound stupid but I need your opinion on it, thank you.
