You can do whatever you want when you are the only player on encrypting data. The problem is interoperability and I imagine "backdoor" that cops want as a way to decrypt tls (which is quite doable, with reasonable safety in mind, to each request you add symmetric key used in data encryption, encrypted with supercop-public-key, distributed on daily bases).
