i can't remember if this has ever been suggested, but in AOTC, could Naboo and Coruscant be merged to form Alderaan? It would require alot of re-matting, and story tweaks, but would stop the two former planets from dominating the PT as much.

this could link with the idea that TPM heralded the beginning of the clone wars, and either a cold war, or a full scale separation has been occurring since. alderaan would act as a sort of switzerland/conference zone for the two sides.

the jedi council would only contact obi-wan and anakin through hologram - UNLESS they had a sort of iconic jedi council space station which they travel around in (like 2001 for us retro fans)
