I think that it would be better if Padme dies because I think it's more impactful. You could redub the medical droid that tells obi wan that she's dying because she lost the will to live and put something like that the babies got hit when anakin choke her. It wouldn't make any sense that Padme stayed with leia and gave luke to uncle owen and aunt beru. Sorry for bad english

everything about this is explained by Obi-wan in the Return of the Jedi...but this aspect is very badly made and poor in ROTS...

I understand your point, it's more impactful and the funeral sequence is beautiful, but it doesn't fit with OT :

Leia : "she died when I was very young"

very young can't mean the day of my birth !! ^_^
