Interesting idea I've had since noticing that the Alderaan is the Capital of the Universe in the comic.
Would have been a cool PT idea if Alderaan was once the planet where the Republic Royal Family lived (Princess Leia being the latest in the line). For generation's they ruled in Peace as nominal heads of state with the Republic Senate alongside. Kinda like ancient Rome.
When the Emperor took over he moved his capital to his home planet, like Stalin building Stalingrad. He deposed the Galactic Royal Family but left them inplace on Alderaan, not then having the strength and support from all the systems to have them openly killed.
So it would be entirely natural that come ANH with the old Senate finally swept away, that he would use the Death Star to crush his old enemies. As far as I recall, there's nothing in the OT to contradict this idea. In which case I might start belieaving that Leia is the "Once and Future (Queen)" of the universe, in my own personnal imagination ;-)
