To work, Disney would have to form a team with a perfect cast.
They would have to find a perfect actress to play Zarda, and she would have to be athletic and hot and wear the famous leotard that Feige hates so much.
This project was born dead because Feige must really hate the 80s Justice League and all versions of Squadron Supreme.
So, I don't believe in this project, why? Just look what Feige did with the MCU Eternals.
