Naboo is retitled "Alderaan", giving the planet some sense of relevance next to the original series. You could argue that Naboo doesn't look like Alderaan, but you have to realise that this fan edit would constitute and alternate canon. The more high-tech cities of Alderaan undoubtedly exist, but away from the magnificent and historical palace of it's royalty featured here.

* Also, some creative voice editing can be used to make reference appear to Alderaan actually in the film. For example Panaka mentions later that a senator from Alderaan is being considered for the position of chancellor. Use this sound bite earlier in the film and Panaka could in fact say "Alderaan has no army!" as opposed to "We have no army!". I think this works even better, because we know this to be true from the original series as well.

I love this idea a lot.

Giving Alderaan large chunks of screen time makes us care a lot more about the place when it's destroyed in ANH and from space the two places look very similar.

It also explains the lack of mention of Naboo and it's people in the OT.

Making this one change binds the saga closer together.
