On the subject of women in Starfleet, I'm pretty sure we never saw a female security officer.
In TOS, no, but in the animated series we saw Lt. Anne Nored in "The Survivor" and an all-female security team in "The Lorelei Signal." There were some female personnel in security colors in the rec-room crowd scene in ST:TMP as well. I don't remember if there were any in the later TOS movies.
I don't have the teleplay to prove it, but I suspect Martha Landon in "The Apple" was supposed to be a security guard, and Shatner addressed her (once I think?) as "Yeoman" from force of habit, or as an ill-informed ad lib.
Landon kicked ass. She was using real karate moves in a brawl, with no cringing and no male assistance. She made Batgirl on ABC look like a ballet dancer!
Early Kirk was the exact same character as Pike; he only became different once the writers began to be influenced by Shatner's performance, and presumably as the network pushed for him to become a more conventional womanizing action hero. And of course McCoy was the exact same character as Boyce. Sometimes I wonder why Roddenberry even changed the names of the characters when they were recast. He kept the original character names when his Genesis II characters were recast (mostly) for Planet Earth, so why change them here? Maybe he already had the idea of incorporating the pilot as a flashback story.
Yeah, he must have been planning from the start to salvage "The Cage," which had been so expensive to make. My first thought would be, just drop it in as a stand-alone episode. Science fiction fans were super-accustomed to anthology series. I'm surprised they didn't do that.
I'd have a narrator say at the top of Act 1, "Years before Captain Kirk took command of the Enterprise, this happened!" Bam. Done.
