Mr. Jackson speaks many times about his 25th Edition DVD on the commentary of the EE Return of the King. Humorously he will add in here or there "Yes, we had a lot more stuff for this scene but it was cut. I guess it'll just end up in the 25th Aniversary Edition." or "I really liked that scene, but we cut it. Someone remind me to put that in the 25th."

So while the plan is a wonderful idea, it won't fill up the missing holes between the movie and the book.

His extra footage that he refers to would not be entire scenes like Tom Bombadil's but little added lines, or additions. Listen to the commentary for exactly what he said.
