I'll go you one better, MagicKyle...
How would you like your phone to greet your callers by name if they appear in your contacts? At all times and not just Quiet Hours...
How about if you called me and heard, "Hello, Kyle. R<> can't come to the phone right now, but leave him a message at the tone," would that be cool enough? Cortana would still send the text during Quiet Hours as well. And Quiet Hours calls that don't break through should be getting your Vmail box and the SMS "busy" message.
