I created this map script for our ranking games. It is ideally mirrored - terrain, rivers, features, natural wonders, starting positions etc (I haven't mirrored ruins as we do not use this random aspect of game).

Example of map generated by this script:

Map script: http://civilization.org.pl/forum/download.php?id=999

Installation: put this map in C:\Program Files\Steam\steamapps\common\sid meier's civilization v\Assets\Maps\

Warning: do not put it in "My Documents\..." - it will cause problems when other player will have it in correct location and you will try to play together

Comments are welcomed, I hope that this map script will be as popular as my mirrored map script for Civ4 LD_Mirror_Inland_Sea (version 1,2,3)
