That's true , but it also depends on the type of franchise you're dealing with. SW isn't as malleable as Disney/Lucasfilm thinks it is. It isn't the MCU, or the DCEU.
They have to tell new stories with new characters , no doubt, but at the end of the day , the question becomes whether general audiences really care that much about a new SW cinematic universe without a Skywalker film in it, stromtroopers vs Rebels, and Jedi's?
Lucasfilm, have to ask themselves what the SW brand is in the eyes of the general audience . Is it a cinematic universe of different unrelated characters each in their own corner of the universe, each with their own adventures? Or is SW Luke Skywalker and the Skywalker family and friends?
In the general audiences eyes, they see it as the latter, and its hard after 40 years to convince them otherwise. . And that doesn't take into account what the Star Wars fanbase thinks it should or shouldn't be.
I think its possible for SW to become more than just the Skywalkers in people's minds, and to tell new stories new characters, but that isn't an easy task when the general audience has been conditioned to viewed the property one way and when the property has basically been made in one way.
Star Wars is old, and I actually think its closer to the Bond franchise which updates things over the years but doesn't really change things that radically, as opposed to something closer to the MCU, which they aspire to be.
They're trying to make it something it was never intended to be to begin with, which makes it much more difficult to really make films which don't fit into audiences and fans notions of what SW should be.
If they want to keep making films that's what they need to do, but I do think they'll limited by what the property is itself and how its perceived.
