New Maulkiller Series Pitch idea

OK, so in the Force Unleashed, the makers of the game decided to make an alternate timeline specifically for the Dark Side ending, and I want to write and animate a new series focusing on that timeline.

Basically, what happens is Galen Marek becomes Darth Starkiller, Palpatine's new apprentice, and decimates the rebellion worse than Vader ever could have. Sometime during the events shortly before the Death Star plans are stolen, Starkiller decides to experiment with the Dark Side and cloning. Flash forward to the events of "Empire", and Starkiller successfully turns Luke Skywalker into his insidious apprentice. Leia and Han, heartbroken by his turn, lose all hope in the Jedi and concoct their own plan. The Rebels break into Lord Starkiller's laboratory and plan to create their own Sith Hero using DNA from Darth Maul to even the odds against the Emperor, Starkiller, and Luke. The Rebels have lost all faith in the Jedi. Now begins a war of the Sith.

idk if this idea seems a bit too metal, or extreme, so let me know what you think.
