Yes! That's what I'm talking about exactly. So, in the opening we see Coruscant,Endor, and then pan over to the DS2.
Instead of Vader going to the DS2, his shuttle travels to Coruscant. Just replace the DS element with a PT Coruscant one. Vader's shuttle travels to Courscant. Add in a shuttle element on Coruscant. Put the matte shot of the large assemblage of troops for his arrival instead of Palps. Vader gets out, but no Jerjerrod. He just travels to the Throne room, high above Coruscant. The emperor rolls his chair around. Out his windows is the city skyline
