I really do like the idea of Luke actually returning to Dagobah before going to Tattooine to rescue Han. And while it looks as though Luke is dabbling in the Dark Side in Jabba’s Palace, I would actually like to see Luke following Obi-Wan’s example but I suppose at the end of the day, he ‘is’ Anakin’s son. Just think of all the unorthodox things Anakin did in the Clone Wars.
The movie should still begin with the Executor being dwarfed by the to be revealed incomplete Death Star and then if that little deleted scene of Vader telepathically communicating with his son could be re-filmed somehow with a little trickery - and then it would be revealed that Luke is in Dagobah in the process of completing his training. How cool would it be if Yoda was there to observe Luke constructing his lightsaber too? If Ady had access to an authentic Yoda muppet, how cool would that be? He built a Wampa from scratch. I suppose building Yoda would be a stretch though.
Thing is though, can Luke fly his X-Wing without R2 as support? He’d have to be on Dagobah too I suppose so sending Threepio to Jabba alone just doesn’t feel right either. He could have accompanied Leia to Tattooine perhaps. Yes, that could work, but how to get him in there? Obviously, Leia met up with Lando and Chewie so maybe it could be established that Threepio was already in the Palace with Lando. So when Boussh (Leia) arrives with Chewie, Threepio can make his appearance at last translating for Jabba.
More food for thought. 😉
