Although not a mod in the strict sense of the word, these building icon sheets have been improved in several ways. 1. The file is a little longer (34 extra entries) and all the icons from the different Conquests scenarios have been added in alphabetical order. The wonders (which have splashes) first and the improvements later. This still leave five spare entries. 2. The industrial era large bank icon has been fixed - see bug report. 3. Geisha and FeifEstab icons have been added to the library and courthouse rows, respectively. With the default settings this changes nothing, put if the corresponding entries are changed in the PediaIcons.txt file from ERA to CULTURE, and the corresponding pedia icon links added, it allows asian civilization to have their own flavor of these improvements.

I am glad I could help! As a bonus, I also attach a post of each icon separately. They have the same names as the corresponding pedia icons, so don't unzip them in the wrong directory!
