What's in a name?

Does anyone know what the likely names were for cancelled projects like TSR-2, F-111K, etc had they ever made it to operational service?
It’s one of the questions that every now and then has floated into my mind, and won’t go away? Surely the minutes of the relevant MoD committee are no longer top secret?
I seem to recall reading once that the name Falcon was bandied about for the P1154.
