Personally it wouldn't bother me, I think it would be an intersting idea. Of course there would be accusations of yaoi and religions such as Roman Catholics would out cry (trust me you'd get some Women's Christian group protesting :P). Although the idea that people follow a religion in the game when you summon creatures (some demon-ish) never seemed to bother them.

However, if it was tastefully done I can see no problem. (I mean they don't wear pink dungarees and say things like "speak to the elbow you're not worth the extension :P)
