If we’re gonna have Hux survive 'til Exegol, I’d really, really, really like to shoot the lightsaber seppuku scene. That said, it might feel strangely out of place without the subplot of him trying to use the Force. Really though, it’s a cool shot, so I’d like to see if we could incorporate it. We’d just use that unused wide shot of Kylo Ren on a star destroyer bridge, crop him out, and add in someone dressed as Hux. After that you just need to have the lightsaber visibly on display at some point in the film, and add a shot of his hand grabbing it. With the right reaction shots thrown in it should work. That said, the more I think about it, the more random and out of place it feels.
