May be possible to alter Ultron's origin and make Tony Stark be his creator instead, it could start out as a presence, like the arm that Tony has in his lab, and then progress into a robot that the Avengers have to deal with. I know that Pym was the inventor of the AI and Ultron eventually kept making new versions of itself until it became a villain.
Still, it wouldn't be the end of the world to tweak Ultron's introduction.
