Possible Christian sub-genres

Okay, I was pondering all the various kinds of fiction genres and sub-genres out there in the secular world. Am thinking it's a shame that we Christian writers don't have more types of writing. Basically it's romance, scifi, fantasy, historical, and I know of someone who writes Christian Asian chick-lit. . Found myself creating some Christian sub-genres.

Christian ecofiction
Christian business fiction
Christian cyber-punk
Christian urban fiction
Christian erotic fiction
Christian ethnic fiction
Christian feminist fiction
Christian outcast-fiction.
Christian lad-lit
Christian missionary-fiction (I think my novel Windfollower might fall into this category.)

Ah we could go on. I think I just want the Christian publishing world to really challenge the secular world.
