Yes. No one on staff is going to read your fan fiction. But if you want to produce your own show you can license the characters or sell sufficient rights or give up enough control that the studio will take it on as either an in house or an out of house project, or you can make it yourself with your own assets and either hope for the best or work out an arrangement with Hasbro as a part of it.
You’re right, they’re not going to make your fanfic. That’s not going to happen. But if you become a writer for them then your screenplays are basically your fanfics, with other people’s notes and direction, for pay.
And if you don’t want to become a writer for the show, or can’t for some reason, then
if you want to make your own show, there’s people who have, and you can, too.
There’s no guarantee that Hasbro won’t shut you down, but you
could land an internship with them and then maybe with your institutions backing you can create a project with them that uses their licensed characters, within the framework of the class project.
They aren’t going to produce your fanfic, and no one is going to help you turn your fanfic into a screenplay. But if you want to write MLP shows, and see your work on the small screen, all you have to do is become a writer for them. People do that, and you can, too.
Look at the Hasbro jobs page, get a degree from the kinds of places the other writers have gotten theirs, get into an internship, and write MLP episodes.
Or, find a bunch of friends an make your own, and either approach Hasbro for permission to do it first, or be ok with a C&D after. People have done both, and to be honest I’m not sure which is worse or better.
