I don’t think that would work.Marvel and Star Wars need put on hiatus. They are no longer an event.
I think they have burned too much goodwill. The reason that Star Wars’ return to the big screen was so monumental was because of how much love people had for the first 6 films and the other materials that kept the fan base alive and fed.
Maybe if marvel took that break after the emotional high of endgame it would have worked.
However now that people have seen the quality drop and look at the franchise with apathy they would need to rebuild the hype for the franchise after a hiatus. Something they are incapable of doing as that would require a good vision, a great execution and patience.
