I agree on some of those things TiiN.

I would love to see Luke building his lightsaber, but I hate the C-3PO standing outside, it looks so fake. Perhaps, Adywan can fix that, and then add the scene in.

The extended bunker scene is cool, but unnecessary, unless you’re making a extended cut of the film.

As far as the Emperor telling Luke his lightsaber is much like his father’s scene. I think everybody just disregards that. I take it as, he built it himself and forget it. It is much like Obi-wan’s saber, because the plans he found for it, were in Ben’s hut.

I think they should show Lando in disguise, but don’t have him lower his mask. This way when you see the Jabba Barge scene and you think Luke is going to die, it’s a big reveal and a surprise to the audience.

As far as the Jedi force ghosts scene, I personally prefer Sebastian Shaw (older Anakin) tnan Hayden’s ghost. However, I don’t know what is in store for The Last Jedi. I know Yoda will be in it, Ewan McGregor will be shooting in early 2019 for a 2020 release, so maybe, just maybe, he’ll shoot a scene for Episode IX, in his older make-up as Obi-wan along with Yoda, and probably Luke Skywalker. This way you have a full circle, Rey looks over to see her master, Luke, his two masters, Yoda and Ben, and Luke’s father, Anakin. This time, there would be four force ghosts, maybe five. (I’m making this all up.)

We just have to wait and see what Yoda and Luke have to say about the force ghosts thing, it might be explained, but probably not. I hope Rian gives us something about it.
