femslash fanwork trope fest?

So I was chatting with a friend today about how one of the sad things about the overall lack of femslash in fandom is that you get less femslash with all the awesome fandom tropes that I enjoy - bodyswap, timeloops, third party realises they're made for each other and sneakily gets them together, so on and so forth.

Gee, says I, there should be a fest or something for that.

Then, says my friend, go make something.

So! Informal polling of the masses, some questions:

1. Would you be interested in such a thing? Should it be just femslash or also female friendships?

2. What format would you like? A community with prompt claiming, a post on my journal for comments with prompts and fanwork responses kink-meme style, something else? I am definitely thinking all fandoms, all kinds of fanworks, for maximum enjoyment. And, ngl, anything that is relatively low-maintenance for me, as I want this to exist but also am busy with other things I need to finish up.

3. And, most importantly, gimme your favourite fandom tropes! What would you like to see for Amy&River, Cara&Kahlan, Toph&Katara, Gwen&Morgana or whoever.

eta: oops, accidentally 3am, should probably go to bed. Carry on, will plan some more in the morning!
