I don’t know if this is exactly what Adywan is thinking, but I still really love this idea. To me, it is a very moving ending and I hope he adopts something like this.
Credit for the effects go to the long lost aalenfae.
Is there any behind the scenes footage of Sebastian Shaw in costume that could be used in the pyre shot? If you put a force ghost shot of him with the ventilator still on but the mask off over the pyre, then have it fade out right before panning up, you could use force ghosts in both shots, and still stick to only Shaw. The film ends with even more of a false sense of security and completion - Luke and Anakin both lay Vader to rest, then we watch both rejoin their comrades.
