Seeing as they're already pseudo hero units as it is, as well as the fact that the Intrigue events from Ways of War have shown that monster models can function as faction leaders, how difficult would it be for someone with some mild experience with the editor tools to make a mod that allows Eldritch Sovereigns to select the Broodmaster model in faction creation?

I'm fairly illiterate when it comes to AoW4 modding, but I would be more than willing to give a monetary tip to someone who could make such a thing possible.
