Did anyone ever watched this video?

I remembered this PMV video featuring the ponies in Corpse Party and decided to rewatch it again because why not then something made me wonder, has anyone ever written a fic set in this? If not, I think I'll be willing to take a shot... if I can handle the feels known to me. Example, if I remember the video correctly, Pinkie is roleplaying for Seiko... Nnnnnooooo, that's going to suck so much!
