Ok, this is basically just an injustice wishlist, but more in-depth. The things you can do are: make the story, name the characters (you can put them in DLC, guest, returning, and new), make arena’s (just say what they are and let us imagine them), and say if it’s gear or skins, if it’s gear make premier skins with established rules. I will be doing all of these in my own post simply so you can make your own know.

And if there dead and you want them in your game, then make some excuse for why there alive. It doesn’t need to be too complicated at all, espiacelly with ra’s al ghoul and the doctor fate god people and klarion (he’s dead, but look at the others and the fact he’s MAGIC!)
