I am all for the kill Lando Idea. It was going to happen up until the final draft I think.
Bingowings, I think your idea of killing off Luke is pretty cool.
But in the end I think the underlying issue is one that even Lawrence Kasdan brought up in an interview I watched. The film lacks a sense of self-sacrafice.
Kasdan wanted to have one of the main characters killed off in the first act. I think he wanted Han Solo to die and so did Harrison Ford. However, George Lucas put a stop to that.
But.... if a major character dies there needs to be a lengthy exposition of it and an emotional response from the other characters. Otherwise it just seems hollow.
I really don't know what Ady has planned. But I am very curious to see how he is going to tinker with ROTJ's storyline.
