That's a pretty fantastic idea. I think even courts will find that the government can't compel you to change your face expression, as they tend to do that for anything the government can't physically force you to do anyway. For instance, they say the government forcing you to unlock with your fingerprint is legal, because the government's agents can use force to put your finger on the phone anyway. So it's legal. But the government can't force you to "remember" your password. So trying to do that is illegal.
