Hard to say
Seems the key players in terms of actual fight choreo aren't actually working on both films, and Damon Caro isn't on SS the way he is with the rest of the dceu it seems.
However snyder is producer so he's bound to technically have the movie he wants made, and more to the point SS has some really talented stunt cords. I'm seeing alot of mad max leads.
But perhaps the key element is Richard Cetrone, he doubles for Affleck in BvS as he did the Comedian in Watchmen(see opening fight), He's doing the stunt fighting for bats in SS it seems(not so much the car ones). I think there is bound to be some carry over.
Cetrone himself is a fight choreographer and is most known to me by his lead work on that show Banshee. Not only is it dope as all hell but, I suspect he himself brings alot of choreo to the table.
