If they do that then they would have to completely alter the entire story of the Silver Surfer and Norrin Radd.
Just because Norrin Radd was named after a male scientist(Norrin Konn) on his home world that was responsible for pulling their society out of barbarism.
Rather than change everything about who Silver Surfer is and alienating his many fans, create a strong female protagonist in the film like Nova, who the Silver Surfer actually saves from a planet in the 1987 comic reiteration. Nova was also a herald of Galactus and would make perfect contextual sense.
I would honestly hate to see the MCU use the panderstone on Silver Surfer.
