If they wiped the post-RotJ EU clean just so they could retell a major story from said EU, it would piss off pretty much everyone. It would straight up disappoint the people who never liked those books and were hoping for something truly original. Meanwhile, it would be like adding insult to injury for the fans that were still holding on to the now "old" continuity.

This is my rationalization and my hope. They have to nail it with this, they can't just rehash EU stuff right off the bat.
