Would it make sense to change Palpatine’s line “The Princess of Alderaan has disrupted my plans” to “The Queen of Alderaan…”? On one hand, the audience knows her as a princess and it wouldn’t make sense to be crowned the queen of a planet that no longer exists, but on the other hand… after all that time, not to mention the death of her parents, wouldn’t she be considered a queen, at least in the eyes of the few remaining Alderaanians?
Continuity-wise, after Leia and another Alderaanian named Evaan Verlaine help the survivors of Alderaan gather, resettle, and hide from the Empire, eventually Evaan is chosen as the new queen (elected Naboo-style, at Leia’s suggestion). It isn’t exactly clear on when that happened, though. The panel in the comic that it happens in is just kind of… ambiguously in the future.
