It was something that I noticed the first time I saw it. Then of course there is the whole Hayden issue...
I've been playing around with a similar shot, myself for ages, recentering it, so the 4 Jedi are in the center of the frame, rather than having Qui-Gon off to the left. I was considering doing multiple angles on Jedi, so that you could see the original ghosts or one that adds Qui-Gon into the fray in the last shot.
I've also tossed around the idea of having a young Yoda, Obi-Wan, and Anakin in the final shot with Qui-Gon as a third option, but that kinda seems like more of a pain than it is worth.
