Texture changes?

Hi,

I am looking for a mod for BI 1.6 that will alter some/all of the skins so they are a little less bright, perhaps more realistic. So like change that awful Sassanid in-your-face blue.

However there's a catch. I mainly only play RTW now for multiplayer. So is there a mod that will edit the look of the units whilst still making me compatible for multiplayer?

This is a long shot, but I really enjoyed playing RTR for 1.5, the realism skins look so great. But I still need multiplayer ;)
