Actually demititans might not be as overpowered as people might think. Look at Hecate's children. She's a Titan but her children are never shown as overpowered or even stronger than the other demigods in Camp Halfblood.

We could still make a representative of God be the Same level of power as a demigod to make it fair. In my opinion I think the character would be some kind of angel that had merged with a human child and given them divine powers to battle demons and monsters
