Hmm, I've thought about actually putting together something along these lines as well, except it was rather more plotcentric (I was thinking of MEPing Anime Academy Heroes but decided it was far too complex, however it followed through with the same idea of pursuing a common goal/theme).
In that same vein, I've thought of a project that would have each track representing a different part of the world. A tragedy or some sort of event leads the world into some combined purpose, and each track shows different anime showing what each of the characters are doing to help out in this global mission. This wasn't exactly the plot I had envisaged for AAH MEP, but pretty close.
Anyway, another idea I had would be something along the lines of a 24 hour theme... the life of a person from their waking moment, through breakfast, lunch and dinner, their school/work life, and their night life, be it they are people who love to go clubbing, or stalk the night as some sort of hero. I had thought of doing a video to this previously, and was thinking of using Clair de Lune (by Debussi (sp?) I think), however that music is probably too short for a MEP.
Out of the ideas you put forward, I definitely like the one that you put the most thought in. Almost like "A History of Anime" so to speak.
I'm definitely interested in participating in something like this, depending on the theme of course, and actually mildly interested as well in heading or helping out in coordinating this if it gets off the ground, but I'm never one to make promises because with my own videos and studio MEPs as well as AMV coordination duties for Manifest, you can say that I'm already stripped for time
