Lucas’ original vision included McGregor’s character ultimately taking on his Jedi Master’s name as part of his attempt to honor his mission to train Anakin. “At the end, as Obi-Wan dies and Qui-Gon defeats Darth Maul and stays with his Master as he passes away, he not only takes on his Master’s quest, but he takes on his name. Qui-Gon becomes Obi-Wan,” McCaig revealed. “That’s why when you see Alec Guinness in A New Hope, he puts his hood down and goes, ‘Obi-Wan? Now that’s a name I’ve not heard.’ Because he’s not Obi-Wan, he’s Qui-Gon
Agree on the attachment concept. Also, the Clone Wars connection of Obi-Wan to Bail Organa was not established while Qui-Gon was still alive, so the continuity of Leia’s holographic plea would have been broken.
