I think it would be awesome if we could choose the portrait of the secondary species if we take the Syncretic Evolution civic. Maybe even their name and description.
I could see this being useful for roleplaying (so we can properly decide our species' history) as well as modding (Goa'uld that have Jaffa as their slaves).
