The problem is a dramatic one, however. Alderaan blowing up in Star Wars barely registers to me, it never did, and main reason for that is that we never see anything of it, or anyone on it who is being destroyed. Sure, blowing up a planet is dramatically impressive, but it's impersonal, and so, for me, emotionally lacking.

That's exactly the reason why I like the idea to change the name of Naboo to Alderaan in the prequels. I don't really care about the problem of two senators from one planet (Padmé and Bail Organa). It would just add that emotion to the scene because you see so much of the planet in the prequels.
