Sorry if it seems like I'm stealing the floor, but here's one of my suggestions:
I'm mixing two ideas together:
The Race
and
Living in Sin
In The Race, The creator
Istiv takes different animes and puts them together and even has them interact with each other by using masking.rotoscoping/etc.
In Living in Sin, the creator
Requiett uses a movie plot, but uses different peoples' voices to recreate the trailer/movie.
My Idea is to combine the two and make something so absurd you'd call me crazy to even announce. We would take a string load of animes with the same type of masking/rotoscoping idea used in The Race, but instead of using a song, we re/create our own movie with our own voices like used in Living in Sin. It may seem out of the blue at first, but it's not impossible. I'll spend this summer seeing if I can make a half decent 5 minute vid or something if this fails....
