I am not sure anything can "save" Star Wars.
It can't be like the MCU, it's too sci-fantasy. MCU is wild but grounded in our world (there's Earth, there's New York, there's the UN etc...) so that gives it mass appeal Star Wars cannot have.
The Last Jedi was the nail in the coffin: they tried going new places and instead of people enjoying the new spin you get the neckbeards crying about how many women are in prominent roles in the movie and how they wanted to see Luke fight the walkers and win
Absolute BS. If Star Wars did not have mass appeal, they would have never made billions on the recent movies, which was almost entirely driven by name recognition. There would be very little, or no, extended universe, of which there is buttloads. No one would have cared about it, 40ish years after the first one. Star Wars has mass appeal in spades.
Hilariously, you seem to not understand how Star Wars would keep making money, yet you already, offensively so, identified who, and how the movie might have not pissed off a lot of fans. Also, its quite sad that you feel people should just "shut up and like it" when movies set in a universe, with decades of backstory, crap all over that universe. New spin, yeah it was, and it was ****. Solo paid the price for it. Ep 9 will be next if Disney does not reel in KK.
Even then it may be too late, because RJ decided subverting every single setup that JJ left for the characters was a really swell idea. It was not, and now JJ has to try to pick the pieces back up and attempt to make a semi coherent trilogy. He deserves a ton of praise if he manages to do it.
