Jordan Catalano said: "I think if this IS true and talks about actresses we’ve been waiting to see on stage again, it might be a show from the 80s or 90s and I’m thinking probably a drama show."
My issue with that is the EP involvement. That signals to me that this is a current show, and a producer trying to make hay with their cast in downtime between seasons (or after the show ends). Like Ryan Murphy working with various TV collaborators in Long Day's Journey and Boys in the Band, or Barbara Broccoli producing Daniel Craig's Macbeth.
An unrelated point:
Given the current turmoil and cost-cutting at Warner Bros Discovery, the owner of HBO, I would be shocked if GILDED AGE is renewed for a third season. It's a costly series, it got entirely shut out of the Emmy nominations save for one category, and its viewership and reviews weren't stellar. Which leaves time for its cast to return to Broadway, and leaving Baranski without a full-time TV gig for the first time since 2009.
