I have several ideas of implementing this. Good armour, but weak attack and spear lethality. Also, I can try and tweak AI formations by making them have all hoplites in guard formation. This way, we can represent the "phalanx". Another idea would be the 0.2 radius, but I am against it since it makes the units very strong.

Also, you didn't answer my question. Will this mod use the BI executable?
