I don't have a definite answer. DC has a history of reinventing their storylines, so DC New 25 could be a partial retelling with some modifications or it could be a completely new take. It depends on how they approach it.
In DC fanfic, Naruto could be considered a god perhaps because of his powerful ninja abilities.
