There's literally no problem unless you want her in another DC comic movie (the initial thread premise). If you do, 'fine enough' plus her asking price, Wonder Woman 1984's box office return, and some (political and thus hard to discuss here) popularity issues are a hurdle.
Honestly, except for Cavill (who seemed like a great Superman in an imperfect solo film) and Leto's Joker (who seems more like your buddy's Ace Ventura impression than a Batman Villain), 'fine enough' has been the order of the day for the characters (various actors have been controversial outside their acting). Even Mamoa's non-Aquaman was a deliberate subversion (one may or may not like) that he carried off well. The problem (again, given the thread premise) is that fine enough doesn't get you asked back.
