Tradition in the AF is you'll have a naming ceremony as a new guy to the squadron. If you were operational, not a newbie out of pilot training, odds are your renaming result would be to keep the old one, especially with a kickass bribe. So it is possible and I've seen it a few times. Henceforth, you'll be referred to as 'callsign' + first letter of last name when people speak of you or if you're both in the room together.
