I’m aware of the fact that this is a very unpopular opinion on this forum, so I hope I will not get crucified.
I don’t like the idea of explaining Leia’s memories in Return of the Jedi in a literal way, that is by making Padmé survive to the events of Revenge of the Sith. Force visions are the best way to explain Leia’s memories, especially when you consider that her descriptions in Return of the Jedi are very vague. In fact, Leia herself said that she only remembered vague images, so I don’t get why they couldn’t just be the product of Force visions. After all, in The Empire Strikes Back it was Yoda himself who said that the Force allows you to see “the future, the past, old friends long gone”, so there is no contradiction really. Also, Padmé being alive at the end of Revenge of the Sith and not appearing in A New Hope is super-jarring, especially if you watch the movies in chronological order, and having her death occur between the two trilogies without actually showing it is not a good idea in my opinion.
