It's already been suggested that Naboo be turned into Alderaan, but what would Coruscant need to be changed/merged?
This isn't the same logic as turning Naboo to Alderaan entirely as previously suggested. This is removing the repetitive environment of coruscant+naboo from the PT slightly, so they are not so repetitive. ie.
TPM Planets
Naboo
Tatooine
Coruscant
AOTC Planets
Alderaan (naboo/coruscant replacement)
Kamino
Tatooine
Geonosis
ROTS Planets
Coruscant
Utapau
Mustafar
Kashyyyk
(Misc inc. Alderaan, Asteroids, Naboo, Tatooine)
ANH Planets
Tatooine
Death Star
Yavin
ESB Planets
Hoth
Asteroids
Dagobah
Bespin
ROTJ Planets
Tatooine
Endor
Death Star II

Alderaan Changes - The whole idea of the planet would need to be re-visualised. It would need to be a metropolis at one point, and empty fields and lakes the next. I would argue to recreate the white city that mcquarrie came up with, and combine it with the period architecture and fashion we get in cloud city. We need a vision of a peaceful paradise.
Narrative Changes - If there was a way, the planet would need a brief exploring before Padme arrives, and the ship explodes. This is still an important storyline as it gets the Jedi into her apartment to protect her. If we have a backdrop of peace, then the explosion would seem even more shocking.
The speeder chase would need drastic editing, as the city would not pass as Alderaan. I would imagine that the chase would begin in the city, then move on to pastures and mountains. It could end perhaps in another urban environment like a floating station?
The Jedi temple could possibly be cut, but I always liked what SSWR did with that scene, as it casts anakin in such a good light, and sets windu up as a potential antagonist. The temple could therefor exist as a space station (which could be incorporated into TPM and ROTS edits). As the Alderaan conference is so important, the Jedi could have a security presence. This space station could also travel to Geonosis later on, although I would fancy it as purely defensive.

Anakin and Padme eloping would then be them moving out to a more remote part of the countryside. Perhaps even an inserted comment that the attackers would expect her to flee back to naboo could be added (i always thought it was a bit obvious). They would carry on as before, and would leave for tatooine as before, then go to geonosis - as before.
These are just IDEAS at the moment. And i haven't thought the entire thing through. Please give it some thought though, as I really think this could be a good thing to talk about. There are still BIG plotholes, but just think of ESB, this is sort of hoth and bespin rolled into one.
