Personally (and you can read why on the Bob's Phone thread) i think that while other places like Berlin and Mexico City might work (in the sense that it would create the same "alienated" feeling that Bob and Charlotte felt), Tokyo was the perfect fit.
For the actors question: It's hard to imagine other actors as Bob and Charlotte (especially b/c Sofia made the role for Bill Murray, and the movie wouldn't have been made if he turned it down...), but I am open to the idea that others could have played their roles. I can only remember one suggestion that someone made from IMDB board, and that was Steve Martin instead of Bill Murray...
it's hard to imagine the movie in another city and other actors playing the parts, because we all love the movie as it is. As a result i think that some will say that the movie could only work as it is (i.e. set in Tokyo, with Bill and Scarlett in it) so try to keep an open mind.
