I’ll limit myself to things that aren’t SE changes or could be done with editing existing material.
Yeah, that’s the mindset I had. The latter part that is. I wanted to focus on changing things that aren’t beyond our abilities to change and wouldn’t disregard a widely known aspect of Canon in doing so. You can change a film’s title for edits all you like, but in conversation it will be forever known by its official title. Same with things like lightsaber color.
