[Star Wars] Luke Skywalker gets killed after being hit on the head by that Tusken Raider on Tatooine. How does the fate of the Galaxy change?

Let's imagine that jumpscare Tusken Raider hits Luke a little TOO hard. How does this change the story from this point onwards?

Obi-Wan discovers the body, sighs and communicates with Yoda, who sighs and sends Obi on a damned fool mission to find and train Leia.  He charters a fast freighter (The Outrider) and figures out where Vader's Star Destoryer went.  Expecting to sneak onto the Executer they soon discover the battle station and use the cargo smuggling trick to sneak aboard the Death Star.  He finds where Leia is being held and mind tricks the Imperial officer in charge of the area into releasing her.  Together they along with R2-D2 and Dash Rendar escape the Death Star and lead the story back to it's normal path.  Wedge and Biggs do the Death Star trench run with Porkins who thanks to Obi Wan's manipulating the Force scores the kill shot on the exhaust port.
