Some way to modify and reset the world gen for a preexisting map

I think it'd be nice to be able to add this into an existing save - Expand the world map, add in new world mines, etc.

I don't think this is possible, but i can look in to it and see if possible. But most likely it will not be possible on a already generated world.
