Here via... my apologies, I can't remember. This list is fantastic! Some stories I haven't read and really, I love fandom clichés more than I should. :)

I also wanted to contribute to your list, if I may. annalazarus had amassed quite a few gender-bender links (http://annalazarus.livejournal.com/1615.html), along with the two that you had linked.

And joyfulgirl41 had also written an Wincesty bodyswap, "give or take the subject or the verb." (http://community.livejournal.com/bday_princess/9407.html#cutid1)
