Besides bringing back Jaylah, I'd also like to see them take the alternative universe idea to its fullest extent on show us "What If?" style alternate outcomes for the characters, or build-up aspects of their backstories that were only hinted at in the films and shows.
For instance, bring back Carol Marcus as Kirk's current partner or ex, and have him have a close(r) relationship with his son David this time. At least, insofar as he Zoom calls him from the ship every day and pays him a visit whenever he returns to home port instead of not being a part of his life at all.
Have a new child Saavik that is the daughter of Spock and Uhura.
Show more of the relationship between Sulu and his husband Ben and their daughter Demora living on Yorktown Station. Have Sulu get command of an alternate universe Excelsior by the end of the film.
McCoy can visit his daughter Joanna and express regret about how his divorce of her mother has driven a wedge between. Scotty can be a father figure to his nephew Peter who decides to pursue a career as a Starfleet Engineer, to his mother's concern.
None of these should be the driving force of the film in any way, but just some nice background filler to let us know what the characters have been up to over the last several years.
