Two Jerks Now Accepting Pitches for Anthology Film #3

Nothing particularly original here. I think we're looking in the right place if we get a Vader as Palpatine's enforcer.

Vader travels the galaxy with his 501st troops as he brings uncooperative star systems to heel. Vader uncovers a plot to assassinate the Emperor by a renegade group of imperial officers, but unbeknownst to him they are assisted by some like-minded Imperial senators, including Mon Mothma, Bail Organa, and Garm Bel Iblis as well as an exiled Jedi. Vader eventually discovers most of the officers involved in the plot, and brings them down swiftly and brutally, one by one, exacting revenge on their families. As Vader tracks down Crix Maxine, the senior officer of the mutiny from whom he plans to extract information implicating the treasonous senators using some savage Dark Side mind tricks, he is confronted by the hidden Jedi, who turns out to be Ahsoka Tano. She manages to stop Vader, allowing Maxine to escape. After a brief duel, Ahsoka also escapes. Vader is conflicted, and reports to Palpatine that he foiled the plot, but does not tell him about Ahsoka. Having survived Vader's wrath, the senators meet in secret, and officially establish the Alliance to Restore The Republic.

Boba Fett hones his skills by hunting big game on exotic planets, and he adopts the Bantha Skull as his emblem. He studies the ways of the ancient Mandalorians, and returns to Kamino to meet with those that helped raise him. He hates the Jedi, but distrusts the Empire. He settles in with unsavory types who rule the seedy underbelly of the Galaxy. He learns several tricks from a new mentor, and eventually joins the guild. Uninterested in even the loose rules of the guild, Fett develops his own code, and becomes bitter rivals with the likes of Bossk and IG-88, Darth Vader learns of the existence of a Jedi in exile, and enlists several bounty hunters to find him. Fett out-smarts, out-pilots, and out-duels his competitors to locate the Jedi in hiding. He reports his findings to Vader, who is impressed.

Obi-Wan spends his first few years keeping a watchful eye on the Lars homestead. Qui-Gon reaches out from the beyond to tell Obi-Wan that he must recover an ancient Jedi Holocron that contains secrets to become one with Force. Obi-Wan reluctantly decides to leave Tatooine, which angers Owen and leads to their falling out. To help him stay under the radar during his journey and not be discovered by Vader, he changes his name to "Ben" Kenobi, and rubs some dirt on his robes to complete the disguise. Obi-Wan takes a winding path to his goal, needing the help of various allies along the way, including Captain Rex, Senator Bail Organa (briefly meeting a young Leia), a rebel operative named Cassian Andor, Yoda, and Qui-Gon. Eventually, his journey takes him to an ancient Jedi temple on Imperial-occupied Jedha, where he is given access to the holocron by a couple of Guardians of the Whills named Chirrut and Baze. Unbeknownst to Obi-Wan while he is deep inside the temple, he was discovered by Imperial troops, and Chirrut and Baze race to stop them from reporting their findings to their superiors (in an ironic flip of the frantic Tantive relay the rebels undertake at the end of Rogue One.). Obi-Wan returns to Tatooine to study the holocron and unlock its secrets.
