The second draft of TPM played with that - “Obi-Wan Kenobi” was the name of the old Jedi Knight who was killed by Darth Maul, and “Qui-Gon Jinn” was his apprentice, who took on his fallen Master’s name in memory of him when he became a Knight.

Oddly enough, Kieron Gillen (who’s written some Darth Vader comics in the Disney era) also used that idea in his Warhammer 40,000 comic about Marneus Calgar - who it turns out was originally named Tacitan as a kid, but took on the name of a fellow Space Marine cadet who was slain by a treacherous instructor.
