Not really, multiple writers have said that Donna and Cassie will have roles in the event. The characters features there are the leaders and representatives of the various Amazons tribes since this is an Amazon event and not a Wonder Family event. The story is about a conflict between the Amazons tribes.

So Scott Snyder was on Word Balloon and confirmed that he was in talks to write a JSA book at one point. Obviously that didn’t happen. DC does seem to be talking to people about it and we have seen several follow ups to teased books (Yang is doing Monkey King after all), so maybe hold on to hope for now? Snyder says JSA is in “really good hands”.
