I can't imagine that anyone would allow that to go down. Lambast Lucas as we do, he did make it perfectly clear that Anakin/Vader's story was over.
What would make the most sense would be to say that the prequel trilogy belonged to Anakin, the sequels to Luke, and the original trilogy to both.
Though that begs the question of who they will bring in to replace the older cast, or if they'll place it far enough in the future that the original cast can reprise their roles
