What If the Snyderverse was fully realized?

Now, the rules of this story might be a bit confusing, but this is basically a world where Zack Snyder is given the keys to make a Justice League trilogy to kick off their new DCEU before a reset that starts the new DCU seamlessly. My reasoning for telling this story is: 1. as a creative challenge; and 2. I believe that the Snyder movies had some promise despite my distaste for his films.
