I really liked having the ghosts be more fluid in the age they wish to present themselves as. So if anything, imo it would probably be a better idea to simply add Shaw’s voice to the Jedi voices scene and that’s it.
Yeah, age-fluidity is an interesting concept for force ghosts. Guess my head canon on that is more purist. And definitely agree, having Shaw’s voiceover would be a great addition to the Jedi voices.
