One thing and I have mentioned it before that I would bring in from the PT into Jedi is that little neckless thing that Anakin made.
It seemed to me to be a Chekhov's Gun that never went off.
When I saw TPM I thought I bet that neckless will actually be used in some way to turn Anakin.
It will turn up at the scene of some disaster or in Obi-Wan's underwear drawer or something but it never happened.
So I thought it would be nice if the one thing Leia had of her mother was the neckless and she gave it to Luke on Endor when he told her he was her brother (he is asking about his mother after all).
When Palpatine is zapping Luke the thing could fall on the floor and that could be the straw that snaps the camel's back.
Otherwise it seems like a big deal for no reason, he makes the object as a little boy, Padme keeps it all her life and it presumably goes up in flames with her body after she dies.
Putting it into the last film turns a small object into a trigger for big events.
