What's your spin off idea?

As Gossip Girl 2021 didn't work, how would you make a spinoff that would work?

Here's mine-

-Henry returns to New York to solve Chuck Bass's death

-1970s prequel of CeCe Rhoades at studio 54 and her occasional run ins with the Vanderbilts

-A reboot but based on the serial killer version of the book Cecily von Ziegesar wrote years after ending the series,

What's yours?
