The one question, I suppose, is how successfully can they build a new Saga (if that is the goal) from completely new and unrelated characters and stories? Will casual fans care? I suppose they could do a 150 year old Yoda as a young Jedi knight...ha.
While not completely unrelated, I think that Rogue One could be a good indicator for this.
Keep in mind that details or a title of the third anthology film still hasn't been announced. It's possible that they are waiting to see how Rogue One does to see if they can do something completely unrelated, or play it say and go with the frequently rumored Boba Fett film instead. Rogue One is going to make money purely on the Star Wars brand, and the Han Solo anthology is going to make money because it's a Han Solo film.
It's also going to matter a great deal on what era and conflict they would choose to focus a new saga around. There's probably a lot of interest in The Old Republic era, and that seems like it would be a great time to canonize Revan in some way.
