I feel adding a Klingon crewman during the Cold War with the Klingons would've had a lot of storytelling potential. Worf would most likely be more hostile to everyone and vice versa
I also suspect there might've been no Cardassian War, so if and when they show up they'd just be hostile rather than outright enemies. But then maybe they'd attack the Federation while it's at war with the Klingons, and when peace finally arrives, Cardassia can't afford the war and retreats, setting the stage for DS9 anyways.
