I agree generally with Neerbs comment however I think adding Leia to this is important and also a really nice transition from her death scene. Sure she isn’t a Jedi master because she derailed her training due to her premonitions about her son but she is a pretty Force-y character. She was Rey’s mentor for training and including her in the array brings the Jedi part of the relationship full circle.
I’d be interested in having Leia be in there only if we could find a nice place to move Leia’s body vanishing. I’m willing to give her the word “Always” in the Jedi voices scene, but a full on ghost wouldn’t work without her body being gone at the time.
And on the topic of “well Anakins body didn’t vanish”, I’ll say that in the edit I have of ROTJ he does. Also, just because it doesn’t happen on screen doesn’t mean it never happened.
