I admit that one of the fics you've never written, to my knowledge, that I've always wanted to read was One Night Together, the story where Kaylee Frye is alone on Serenity, making some repairs after a particularly trying job, and really dives into the relationship the two have with one another. (Kaylee x Serenity OTP ;)

Of course, in the Avengers universe, I was really looking forward to that fic you never wrote about the time Bruce and Tony... oh, well, I don't want to give it away. I think that was called Biochemical Engineering for obvious reasons. (I think what I liked most about that story was that, all too often it's like, oh if two people are that close they're obviously romantically involved, but this showed that isn't always true, you know?)
