Re: Would you like for Chapel to appear in a new movie?
On the subject of gender swap, I remember years ago reading an offical Star Trek short story, not unlicenced fan fic, where the Enterprise crew is gender swapped for some bizarre reason, except for Spock, and it was pretty clear that he was attracted to lady Kirk. I wish I knew what that was from, it would be from the 70s or 80s. I'm amazed that got published, but like the slash-tastic novel Killing Time, these things slipped thru now and then.
During that time period, there were two books published by Pocket (or whoever held the license) that were collections of fan fiction, under the titles New Voyages and New Voyages II. I think the editors were Marshak and Culbreath, but I can't connect to Memory Alpha to confirm. Could that be where you read it?
