I can't imagine such a feature will be added, because translating a 2-D paper image into a 3D map seems like it would produce at best, something which needs to be rebuilt by hand anyway. There is absolutely nothing, whatsoever, "simple" about it.
True...however implementing a topographical map rendering tool...now that would save time in creating a basic landscape...to be later skinned of course.
A city map (overhead view) could also be great to make a basic street and foundation start...also to be skinned and buildings to be constructed on the foundations.
