I wonder if the Kelvin characters should adopt alternate fates from ideas left on the cutting room floor from the TOS movies and GEN. As like a post-Starfleet career thing, and have the characters take a radical departure from their depiction.
- Uhura hosts a radio show, or is doing a Doctors Without Borders thing
- Scotty is a Professor of Engineering, taking captured Klingon ships apart in front of his students
- Sulu became captain of the Reliant, and then retired to be a cab driver on a backwater alien planet; he maintains some sort of personal connect to great-great-great grandfather (maybe home videos spliced together from the mid 1980s (child), mid 2020s (middle aged) and mid 2050s/mid 2060s(elderly, played by Takei?). Also, his husband Ben is dead and Sulu raised Demora alone.
- Chekov either became a chess grandmaster, was V’ger’d, ended up in a different universe or timeline, or was simply reassigned to a different ship or starbase. Maybe he took over the Reliant from Sulu and is exploring Cardassian space during the next movie. IDK what to do with Chekov really. But it will be an elephant in the room that would need to be addressed if there is another movie. And I feel that Jaylah could have evolved to be a chess grandmaster herself at the Academy.
- Kirk, Spock and Bones had a major falling out with each other after BEY and go their separate ways:
Kirk is revealed to have fathered a child with Janice Rand from a fling during his days at the Academy (he’d be the Uhura to her Spock in this case); his child had grown up and leads a rebellion on a Federation colony. Kirk orbital basejumps competitively with Scotty and Jaylah as his support team. Kirk is also revealed to be dyslexic. Maybe he did have a fling with Carol Marcus’s sister-in-law Janet Wallace between his Academy days and BEY and that is the reason Carol left the Enterprise
Spock has a relationship with Sybok, but his mission status is classified; he’s preoccupied with death, maybe from being resuscitated in a Klingon sickbay, or because of Spock Prime; Saavik is still his student, though she is in this universe half-Romulan and half-Vulcan. And she is suspected of being a traitor and caught up in conspiracies. This always put him on the defense to protect Saavik
Bones has become is a follower of Sybok, joining him on his voyage to Sha-ka-ree, and is dating a member of Sybok’s following
- USS Enterprise-A features saucer separation, and its used often on Constitution class ships. Could be borne out of Kirk’s encounter with the Krall and the Swarm.
- The Romulans don’t really do much in TOS movies. But what if they went with the original idea for TSFS and the Romulans sought out Genesis in the Kelvin timeline? And the Romulan captain kills someone close to Kirk – either his mother Winona, his brother Sam, or Carol Marcus. Maybe Saavik is aligned with them and is the one to deliver the Winona/Sam/Carol is dead message, like how Saavik Prime delivered the “David is dead” message.
- If they go down the Khan well again (I would not be surprised if they really wanted to), Marla McGivers is alive and a witness to her husband Khan’s reign of terror. Maybe Khan does destroy a planet with Genesis and does develop psychic powers to fight Kirk. And does whatever possible to damage Kirk’s name.
- If they do another revenge story, I would not mind seeing Shahna relentlessly seeking revenge on Kirk like Khan. Kirk being pursued by a jilted lover would be a different revenge plot than usual. They could probably cast Lady Gaga in the Shanha role.
