If you could, yeah.
I mean, I know you could do anything you want, I'm talking more like... Do it in a socially acceptable way? Like, you can say "I worship the Lord of light from game of thrones" and people would be all like "Wow, that's cool- what temple do you attend? My friend goes to the one on Union street and she swears the high priest there plays with his junk under his robes when giving a sermon."
