I have no skill in programming, but I have an idea for a mod that I think would be very fun.
Any time a player researches a tech, its allies would get it immediately for free, even if they wouldn't normally have access to it, including unique techs.
A Civ wouldn't have access to units they didn't have access before, unless it is an upgrade for a unit they already have.
If you have Light Cavalry, but not Hussard, you can get if your ally researches it, but if you are using a meso-american Civ, you don't (the exception being cases like Timurid Siegecraft that one of the benefits being exactly to give access to the Flaming Camel).
A team with Bohemians, Ethiopians, Portuguese and Celts could have Houfnice with Wagenburg Tactics, Torsion Engines, Arquebus and Furor Celtica, as an example.
