What if Rey’s training course and Force vision came after the scene where Poe accuses her of not doing enough to help the Resistance? That way her frustration and anger in that scene would have a more palpable cause (rather than her smiling contently at Leia, and then going immediately apeshit on the training remote). Rey could go from her failed meditation session to speaking with Leia in the hanger; then later, a hard cut from Poe telling her “We need you” to the training scene (cutting her line about “What’s the message?”), and then a cut from the training course to everyone listening to Palpy’s message.
I feel like that would be a better transition tonally than we got in the original film, not to mention a better motivation for her pushing herself so hard during the training course than…nothing? It goes from angry Rey, to “What was all that evil stuff?” to “Oh noes, the Emperor is back! That was the evil stuff!”, as opposed to the original through line of “Ha ha, fun banter! Oh crap, it’s the lord of all evil.” The only iffy thing would be trimming/rearranging some of the dialogue, but I think it would be possible.
