I need 7 psionic empires to play with my friends

Hi everybody! Im gettin the new psionic DLC and me and my buddies (2 of them) are gonna play as one empire of mindwardens and we want it to have really cooool headcannon, so we are gonna play determined exterminators and thought to have 6 other psionic empires as the npc's. I know theres no way to guarantee what they choose to ascend as apart from a few origins, and me and my buddies arent very creative when it comes to making empires (we like big alloys and fleets and we cannot lie) so i was wondering if you guys could post some builds that kinda guarantee (as close as possible) a psionic ascension for us to force spawn in the empires. Any builds are super appreciated! Thanks everybody!
