I have been wondering if we might see Ghost Anakin giving advice to Luke on helping keep his grandchildren from falling to the dark side after Solos killed in the action of the first couple minutes of the film. I could see them beginning with an assassination of Han and Leia by the new Baddie, Darth Fillintheblank. Jaina or Anakin then vow revenge and Luke and Ben Skywalker must hunt them down and stop them from falling to the dark side. Also, you could have a major conflict in the middle with General Calrissian and General Antilles trying to keep the New Republic from falling to a new enemy. I would also love them going to the Imperial Remnant and ask for help and have the Remnant turn out to be the good guys in this one.
