An idea I’ve had for a while but don’t think I’ve ever shared: to better parallel the Blue-vs-Blue duel from RotS, have the Skywalker lightsaber be red during the duel on Kef-Bir. (This would also just make the duel more visually striking, I think).
It wouldn’t have to be Red for the whole movie - it could turn red when Rey activates it in the Throne Room (implying that her vision in the vault made the crystal bleed) and then it could turn blue again when Ben gets it on Exegol.
I’ve tried editing this in myself but it’s very tedious - and given how quickly the edit that turns Leia’s Saber purple was made, presumably there are some people here for whom it’s easier (and the amount of time the lightsaber spends on screen between the throne room and the KoR fight isn’t much longer than the amount of screen time Leia’s saber got).
So if anyone else is interested in actually doing this I’d love to know.
