Story Idea

I'm currently trying to come up with a loose plot for an utterly OP, completely insane and evil Twilight story where she gets found torturing and killing her friends, and barely escaping Celestia and Luna with her life, goes around finding items of great power. Not limited to solely items of Dark Magic either. Mastering every type and branch of magic, she comes back with an army of skeletons, Griffons, and Dragons, big fight scene, a "happy" ending where she wins and, being immortal, will always rule. Possible sequel where she fights off a cliche uprising while trying to conquer the rest of the world. She still wins because I hate when authors make sequels where she loses. Somewhat inspired by Rise of Empress Midnight.

Would anyone read that?

I would like help coming up with ideas, plot elements, etc.
And Betas/proofreaders.

This is, of course, if anyone would be interested.
