Is it possible to expand the 21-tile city range?

[Trade-peror]

The 21-tile city range, in the shape of a "fat X," sometimes forces strange city placement to get certain resources. Is there any way to modify this range/shape? I would like to see a 32-tile range, which would incidentally also fit in the city screen display. Of course, being able to modify the city screen display (such as through implementing scroll bars) would be even more incredible...

Perhaps with the SDK. You can learn c++ while waiting for it (if you don't already know it).
