After watching The Last Jedi, I’m considering having the Yoda disappear after the fight with Dooku, to reveal that he has not left Coruscant. Cutting to the footage of him in his meditation chamber after the Tusken Massacre. This helps explain his sudden limberness.
I also plan on exploring further other force abilities…
This way when Anakin complains that there are thing they are not telling him it doesn’t completely come out of nowhere.
I like this idea, but I think you still need to cut the lightsaber duel itself as many others have done so you don’t run into the inconsistency of Yoda’s projection making physical contact in a duel while Luke’s never did.
