Problems:
- If you wanted to be able to latch them closed sometimes I'm not sure of the best way, especially if you wanted to be able to lock them from the inside then unlock them from the outside.
- You'd have to build them very precisely to get them to swing easily but still block noise when they're closed.
- Getting the swinging action right (so you don't have to push them too hard and they don't swing closed noisily or too quickly) would be hard. I suspect cams would be better than springs but it would be a custom-building challenge.
