Dark Agenda has announced the Racebending Revenge Ficathon:

Re-write one or more white characters in the fandom(s) of your choice as chromatic/non-white/PoC, in a story of at least 500 words, with some acknowledgment of how the racial difference would make a difference to the story being told.

Details and sign-ups are here.

If you plan on writing something for the ficathon, feel free to also post it here. :)
