i guess a problem with making alderaan/naboo capital would be two things though,
a) queen of naboo/alderaan, would that make her leader of the republic? or does naboo just act as a standing area for the senate
b) when naboo gets invaded by trade federation (or proto seperatists) i would expect a greater responce, unless the republic was too afraid to ask, and the jedi were acting more as infiltrators.
Padme Organa....hmm, if only we could change her first name to flow better.
