Welcome The Concierge, your idea is interesting I'm not sure how to work it in to ROTJ, could Padme become a Force ghost when Mace couldn't? It could be a dying dream of Anakin but that might get in the way of the pacing of those crucially fast paced scenes.

I'll have a think about how it might be done.

In my silent edit I just used some few frames of Padme crying (from ROTS) when Vader is looking at Luke when the Emperor is killing him.

That way we can connect with the PT (although it is not the taste of everybody) without having to show another silly ghost. It shows that Vader still remember her and it could even work without the PT because of all the talking about Luke's mother before. The audience should guess this "new" character have to be Luke's mother and the lost love of Anakin.
