help me brainstorm -- should I hold a "50 Years of Doctor Who" ficathon?

Hello, internet! (Well, probably my flist, but you guys are all AWESOME.)

As we know, Doctor Who is about to turn 50 years old! We've had Eleven Doctors so far, and lots of assistants/companions, and boatloads of villains, and TARDIS-loads of one-off characters. And that doesn't even count spinoffs and other media, like Sarah Jane Adventures and Big Finish. As far as fanfic goes, the Whoniverse fandom is a character extravaganza!

However, a quick look at the Teaspoon category counts shows that certain characters are written a lot more often than other characters. Well, that's natural, and there's nothing inherently wrong with it. But wouldn't it be great to have a ficathon that celebrates the upcoming 50th anniversary by encouraging fic that comes from all 50 years? (Okay, 36 years of actually being on the air . . .)

What do you all think? If I were to host such a thing, would you be interested in taking part? Also, any ideas on how best to run it? Here's what I'm thinking so far:
