There WERE actually studies about basically having a big puck of fireproof foam with a seat on the back. You sit in the chair, and then backflip into the atmosphere. It works because you are going so damn fast the plasma kicked up from reentry can't catch up to the back of the heat shield to roast you. The biggest problem is the infrared air-frying (vacuum frying?) you, but a space suit should be able to handle that much.
