Oh yes, red lightning is absolutely videogamey and tacky, but the final battle is already Rey making Palpatine explode by using two lightsabers and channelling all the Jedi, so (like with Jonh’s ghosts) I feel like it works better to lean further in to that rather than try to mitigate it. We can’t easily fundamentally change the third act of this movie through fanediting, unfortunately. I feel red lightning makes for a much more visually interesting contrast rather than having even more blue on blue; it better conveys that sense of Rey (and Jonh’s ghosts if present) struggling to hold back the overwhelming power of Palpatine; and the poster promised me some red lightning damn it!
