I am not asking for any work to be done for me, and I have already searched the forum for an answer to this, so here goes. Before embarking upon making this mod myself, I simply want to know if this is known to be impossible. I have grown pretty fond of playing from the "diamond-grid" perspective, that is with the grid on and at a 45 degree angle, camera facing northwest. While I am aware that you would have to mess with map scripts to an extreme degree and make a nonsquare map to place "north and south" at the north and south ends of a diamond grid, I really don't require this.

What I wish to do is rotate all the cities by 45 degrees so that they have roughly the same perspective as you have in square-grid view. I also would like to re-orient the minimap and mod it into a diamond shape. I do not intend to actually make a real change to the map, the north would be "north-east" and the south would be "south west" after the rotation. Is this likely to be possible, or will I run afoul of hard coding if I try to do this?
