I like the red lightning idea just because it breaks up the MAXIMUM BLUE aesthetic of the movie. Here’s a short mockup clip using the very laziest AE hue changing shapes. Obviously that’s just a quick edit; not using any of the luts or Jonh’s edits, but you can see what it might look like if someone did decide to edit in MAXIMUM RED lightning.
That’s cool as hell, I’d def like to see a legitimate/full version- especially the part where Palpatine disables the entire galactic militia in the sky.
