Not a bad Idea.... There is a reason he is written to be as powerful as he is. He is the son of the chosen one. GL said that Anakin wasn't able to reach his full potential but maybe the son could. Anakin was supposed to be more powerful then any other Sith or Jedi ever to live and now Luke is becoming that person instead of Anakin. The problem is, is how do you write a character that is meant to be so powerful. You can't always have a big bad sith that is at his level for him to deal with. What they need to do is change his roll s little bit. Give him more of a roll like Yoda. Yoda new he was the most powerful Jedi in the order at the time but he still stayed at the temple and lit his students take care of his orders. Maybe Jaina is being set up to take his place somewhat . The force did name her sword of the Jedi. Or Ben, I think I would prefer it to be Ben.
