Could be good. Will withhold judgment. In addition to needing to strike the right notes with the origin story/introduction, you also have to cast the right actress. I'm sure Benoist will want it, but they will almost definitely go a different direction to avoid confusion. They don't want to be pigeonholed into the story the series has been telling and it makes no sense to cast the same actress as a different incarnation of the character.
I've brought this up numerous times but it was heavily rumored that WB was making Bale a huge offer to be Batman/Wayne again in Batman vs. Supes but it was not going to be the same Batman/Bruce Wayne from the Nolanverse. Imagine having the same actor as a different version of that character. It would be so bizarre and confusing.
