No director should be overseeing an expansive shared universe project. Directors will not fire themselves. Kathleen Kennedy at Lucasfilm and Kevin Fiege at Marvel show it needs to be led by a producer.
So no to Patty Jenkins. I feel like she can be utilised to direct non-Wonder Woman projects as well, particularly those with female protagonists.
No to Joss Whedon. The guy is toxic right now. His "feminist pass" has been revoked since people saw the draft of his Wonder Woman script and his ex-wife exposed him recently as a hypocrite when it came to women. Nobody wants to see him direct a Batgirl film (if the must make that, give it to Jenkins).
Geoff Johns is an overrated "yes man". He likes everything, till it gets pointed out it's not good, then he turns on it. He was pimping Martin Campbell's Green Lantern film (he was a story consultant and co-producer) till everyone pointed out it was crap. He does not know how to lead a film universe as a producer. He lacks the right instincts.
I don't want "film people" whose knowledge of the DC Universe characters is limited to having seen some WB movies, to run the show. That's how they got into this mess in the first place.
It's tough to say. You need someone who knows and understands the DC characters intimately, but also knows the film producing business well, and how to handle budgets.
I think getting the original animated universe team of Paul Dini and Bruce Timm (and getting Alan Burnett out of retirement) could potentially excite fans as the overseers. Animation and live film is different, but there's enough crossover skills needed on the production side of things for these guys to have to competence to overseer a live action division.
