I love Damian but I agree. A title with "Super" in it suggests well, two "supers".
But again I wholly expect this scenario because the default answer to any question at DC is "add Batman or a Batman-related character".
Here's a twist of an idea, Jon Kent from the pre-Flashpoint verse and the future son of Superman and Wonder Woman from the current verse. That would be a weird dynamic. Kinda like step-brothers only..not, lol.
