What I was suggesting was just cosmetic - change LH & names - use the same city lists, etc. you had for Chola in the earler AD versions. Use the same civ traits, etc. you had in mind for Maurya. Not at all suggesting you change the overall design for the mod. Purely your choice.
Thinking about it, I might just leave things as they are at the moment and bring the Chola & Veneti in when I do the first altered BIQ.
I have some civilopedia previews for those who are interested. Rather than put them up here, I'll link directly to the preview page on the website:

Note that every element that's going into the mod, be it a building, unit, resource, tech or whatever, is getting it's own unique civilopedia entry - i.e. descriptive text that you can find out more about the building/unit/resource/tech.
