Casting Legacy

Let's say this series will be unoriginal and straight duplicate the movies. Mostly because this is the fear of many. Post each of the movie main characters, who plays that part now, and what will happen if that is the case. EXAMPLE
Movies vs LOTF
Sidious-Lumiya
Vader-Jacen
Obi-Luke
Luke-Ben
Story-Jacen can't kill Ben, turns on her and kills her.
or
Sidious-Jacen
Vader-Ben/new apprentice chosen by Jacen
Obi-Luke
Luke-whoever gets to fight them (Jaina?)
Story-She goes against them and turns Ben, they take out Jacen or manage to turn him.
or
Sidious-Jacen
Vader-Ben
Luke-old Luke
Luke confronts them, maybe with Mara, Ben can't kill them and they take out Jacen.
Or Jacen is the new Luke, who turns from the dark side, kills Lumiya and an unknown other, saving the day. Once Luke/Ben/Leia/Jaina convince him.

Not a Literature topic.

 

Huh?

 

Lumiya will be played by Jack Black. The rest of the cast will be Muppets.

EDIT: And my post causes an insta-lock.
