You make him a complication, not a main or even primary supporting character.
Did the "Fake Buzz" steal the focus of Toy Story 2 away from Woody?
No, because he was designed to stand in the way from the real one saving Woody.
Similarly, if Batman has a particular function, performs that function, then leaves, MOS2 can still be "Superman's movie."
But that would take a sense of intelligence, tact, and boldness on the part of the storytellers. Let's hope for the best.
