Geo,

If the mod has an Empires folder, I'd add a folder for each custom set with at least the set's inventory layout file and its [Empire]_AI_Main.txt file. It might be a good idea to edit the two entries that point to script files to use the default ones.

ie:

From:
AI Script File := [Race Name]\[Race Name]_Main_Script.csf
AI Script Empire Setup File := [Race Name]\[Race Name]_Setup_Script.csf

To:
AI Script File := Default\Default_Main_Script.csf
AI Script Empire Setup File := Default\Default_Setup_Script.csf
