Take a casual look at the canon builds of Vtorusha and Aat. This tells us that a Sibling counts as a special type of Companion that doesn't eat any slots.

Open up the Languages slot. Choose the Bilingual bonus of any ONE of the following: Palatiner or Elven-Northerner. This works because Siblings are a type of Companion.

Buy infinite Siblings. Fill their death slots with Izhitsa. Divide your infinite destiny points into three pools: one to Burn the Future and pay off the siblings, one to Burn the Future and save for later, and another one to save for the same.

You have infinite Ancestry and Destiny points. Buy the God-Script. Assign Izhitsa to your Siblings. Become the fourth Elder God of the new world.
