Modding difficulty

[Jambo]

Great idea! The bigger units would have to not cost any more in terms of denari or population though, but that being taken as a given, then this is a superb idea. I'd like to fight more/bigger AI armies, rather than artificially boosted ones we have at present.

EDIT: In terms of actually answering your question, alas I do not think this is possible given the files we're currently able to mod.
