97 Legend of Balrog

Hey guys, I've been hard at work on trying to design the characters for the novel as well as the story board, and while I was doing some thinking I came up with an idea that I wanna run past you guys. Get your opinion on it.

How would you guys feel if I included some pagan deities. The basic definition for those who are wondering refers to a pagan as anyone who worships a polytheistic or pre-Christian religion such as the greek, roman, and norse gods. Now the idea isn't that they are their all-powerful counterparts, but creations created by the Christian God. Just men and women with more power than a normal human.

Or should I stick to the original idea and theme and just keep it centered around humans, demons, and angels?
