I guess since there is such an air of mystery around this God, it does give your the reins to do whatever you want with him.
I mean, look at what they did to Thor and the Nose mythology (Marvel), and that stuff is pretty well documented. I guess just look at the culture and how the other Gods are depicted as to keep to the theme in regards to character and story?
As long as you are respectful of the culture I guess there isn't anything really stopping you from doing anything with the character!
