How would all of Uruk from FGO's Babylonia Singularity under Caster Gilgamesh's rule fare In the New World from Overlord as a nation state?

Gilgamesh and the entirety of Uruk gets teleported to the New World smack dabbed between Roble/the Abelion Hills & Slane Theocracy. He gets access to every item he should realistically have as Caster Gil (No EA cuz he gave it up, most of the Gates of Babylon is given to his people) aswell as his servants like King Leonidas, Merlin, Ushiwakamaru, Ibaraki-Douji, Amakusa Shirou, Benkei, Tomoe Gozen & Fuuma Kotarou. He as a Kingdom must deal with the power/politics of the rest of the New World aswell as the threat of Nazarick looming over their heads. How do they fair as a Nation in the Overlord series?
