I think they should make:
1: A jedi and clone battlepack. Jedi: 2 jedi with 1 saber, 1 jedi with 2 sabers and 1 jedi with a double bladed saber. Clone: 3 clone troopers and ep 3 anakin with a blue lightsaber,black cape and hood.
2: Mustafar control room. minifigs: ep 3 anakin with blue saber, black hood and cape, 4 security battle droids, nute gunray, wat tambor and other seperatists.
3: yoda vs palpatine. minifigs: yoda with green saber and emporer palpatine with black cape, hood and red lightsaber.
4:anakin's dreams pack. minifigs: shmi, tusken raiders with gaffeti sticks, padme and obi-wan with brown cape.
5: birth of the twins. minifigs: padme, nurse droid, baby luke and leia, obi-wan, yoda and bail organa.
I'll come up with more, I just need to think of the first.
