Proooooobably not worth mentioning, but in light of Palpatine having his skin melted/torn off his body from force lightning at the end of ROS, would it make sense to include Palpatine being disfigured from his force lightning in LOE? I feel like there’s always been an argument over whether Palpatine was hiding his true form prior to being “lightninged” in ROTS or if he was truly disfigured from the process. ROS seems to clarify that, but maybe I’m reading into it.
Also, I know you deeply want to leave these edits alone at this point so feel free to ignore this post.
If anything I’d say TROS clarifies the situation in a way that fits better with LOE as is. In TROS when Palpatine is rejuvenated he has the melted look, which implies that is his true visage.
