I would just prefer seeing Hattsuli III as a Servant, seeing when he faced the Servants in Fragments he compared their battle to the one he had with the Hittites.
Plus I'm curious on the strength of a king who ruled Egypt's greatest rival and who faced it's greatest king in battle. If anything according to Ozy the reason why his temple walls can withstand Anti-Army NPs is because of the Hittite Iron they are made of.
