Personally I wouldn’t mind if there was a fair amount of story appropriate time jumping in the series, a lot of us probably would enjoy Qui-Gon as a force ghost but I also like the idea of limited flashbacks, even playing with the ages considering that’s basically the new CGI trope these days.
My ideal version would be old Ben, the wandering Jedi, roaming the desert in hiding, maybe caught between the dilemma of helping another or exposing himself to the new Empire on high alert to track him down, interspersed with reflective moments ruminating over his past with some familiar faces, some prequel redemption.
Sort of like…El Camino?
