Modding Urban Development?

[aarne_vaarna]

Specifically, is it possible to mod the game use the apparently geographically based WW2 and Cold War era urban settlement graphics after Economic Revitalization or in the 2020 scenarios? For example, through replacing graphics files? I rather like the more varied and detailed urban graphics of the previous Urban Development levels, and would like to keep on having them (or start with them).

While on the subject, would it be possible to mod the game to hide constructed buildings in the WW2 and Cold War era Large City upwards size urban hexes like the 2020 urban hexes do?


Thanks in advance.
