I had a thought about whether the “Luke trains Leia” scene could be used as a night training scene between Luke and Rey? We already know Luke’s going to have his Green Lightsaber at the end of TLJ and by possibly reframing the fight as being Rey’s “turning point” in her intense but advancing training with Luke could make much more sense why we the audience feel she’s becoming a worthy successor.

From your comments it’s clear that your edit will make it seem like Rey has been training with Luke for a while. How long is it in your headcanon for this edit?

I’ve always felt that if the ST had let Rey train with Luke for a few months at least it would’ve been much more believable.

I’m currently toying around with one of the scenes where Rey is silhouetted against Ach-Toh training in the sunset and trying to colour and edit it to create the same scene but appearing in a variety of conditions (Sunset, Sunrise, Night, Day, Rain, Snow) and making them snapcut together giving a quick 10 or 20 second impression of days or weeks passing between lessons and scenes on Ach-Toh.
