I've seen a mod or two like that.
As for the OP question, I think it's silly not to say the Italian civilization is in gamplay as the later iterations of the Roman Empire. Despite the post-Fall Germanic coloring, Italian civilization is very much a continuation of Rome's. There's a reason why the word Renaissance starts with the suffix "re-". It was return to the roots of their own intellectual heritage and a countervalent to the influence of that middle east import called Christianity.
Christianity was born in Roman territory, and is a completely Roman religion. And Italians were Catholic, which is more Italian than than the semi-Greek pagan religion of the late Republic.
