Actually, to be more specific, Spock almost killed Kirk because of pon farr. But I digress...

To answer your question, it would be against continuity because of this: Vulcan males are supposed to go through pon farr every seventh year of their adult life, beginning in puberty. In the aforementioned "Amok Time," Spock tells Kirk that he had hoped his human blood would keep him from having to go through it, implying that it had never happened before. Maybe his human blood did delay it until well into adulthood. But if the 2nd season was his first time, it sure couldn't happen in a movie that's supposed to take place before that.
