Sawing off the serial numbers in the fanfic chop shop

Welcome to the Fanfiction Chop Shop, where fanfics are taken apart and turned into "real" fiction for the sake of creative writing instructors.

Here we demonstrate that the fanfic author can write, so that said professor will allow a certain fanfic author (namely, me) to include Nanowrimo as part of the creative writing class in the fall.

Cool, huh?

Here's the trick: It can't even look like fanfiction by the time I'm done with it. In fact, he's even iffy about genre fiction, but willing to observe a genre fic that has strong characterization and a plot that doesn't hinge on the cool sci-fi/magical shit.

This means the story I slice apart and buff a little (or a lot) needs to demonstrate:

1) I can write plot, a discernable story arc
2) I can write believable characters (trickier than you think with fanfiction, because we're riffing off canon we already know)
3) I can write setting
4) I can write a clear and consistent character POV
5) it can't be porn

Damn. Yeah. That last one's a toughie. That just took out almost all of my stories (so much for Beg Me For It).

So, the chop shop door is open. Seedy-looking criminals are ready with the grinders, welding equipment, and paint to take a story apart. Now I just need your opinion. Which story or stories should I try to turn into "original" fiction? What's doable do ya think?

ETA: Sorry this is so wide. I wrote my own poll code and didn't know the text box would do that. Grgh. It won't let me edit the poll.

ETA2: Darn. I forgot to include Traces Through Time. Pretend it's there.
