Honestly, I think a reboot of the franchise did make sense. I would completely change the backstory of Luke Skywalker and the other Jedi to give them more of a role in the series.
Instead of being raised by his aunt and uncle on Tatooine, Luke after he was separated at birth from his mother and twin sister, was taken to train with Obi-Wan in the Jedi arts on another world. Leia was sent to train with Yoda at a young age as well. During their time in training Obi-Wan and Yoda work quietly together to secretly rebuild the numbers of the Jedi to several dozen individuals in secret and recruit Force sensitives across the galaxy.
Bail Organa does call out to both Jedi after learning of the existence of the Death Star to destroy it. With the help of some of their Jedi pilots, the rebels do manage to destroy the station and achieve a victory. Obi-Wan is probably killed leaving is a section of the remaining Jedi Knights to become isolated from where to find Yoda and other survivors of the order for several years.
Darth Vader learns that his former master, in fact, created a new order of Jedi training in secret and becomes more personally involved in the search for the Rebellion headquarters which could still move to Hoth. Yavin could also remain undetected as Rebel Central too because the main protagonists don't fly back there and allow themselves to be tracked.
A secret communication calls the spirit of Obi-Wan to guide his students to Degobah, where others are being trained as Jedi. Some of their numbers are captured by the Empire and lead them to disobey and to be killed or captured themselves in a trap set up by Darth Vader. Luke is amongst them and learns, in fact, Darth Vader is his father.
Upon returning to the secret Jedi Academy for training, Luke confronts Yoda and Obi-Wan for this apparent deception in front of the others. Like before it remains peacefully resolved. Yoda also remains peacefully on his deathbed.
Working with the Rebel Alliance, they learn the Emperor is, in fact, present at the Imperial Palace on Coruscant meeting with Darth Vader. They stage a guerilla attack aimed at destroying the palace and eliminating both Vader and the Emperor at the same time. Many Jedi ally with this effort. The first wave of the attack turns out to be a trap designed for the fleet to be picked off by the Imperial Navy.
When it doesn't go as planned, some of the Jedi fully trained land at the Imperial Palace where they do have a confrontation with Vader and the Emperor. The scattered forces of the Rebel task force eventually regroup after evading the Empire and with reinforcements make a successful decapitation strike on the capital. Because of his son, Vader is still redeemed and destroys the Emperor.
The Rebellion rejoices and those who survive this encounter with the Empire go on to restore the Jedi Order under the protection of the New Republic.
If we do go into a sequel series of films with it, Luke has trained a brand new academy, one of his students is recruited by warlords that rule over the Empire, sells out its location for power, and it's destroyed. The surviving Jedi once again are forced to go into exile and start over again.
