What do you do with Vampires in Space?

Just Some Thoughts On A Story 

I started a story not too long ago for an anthology. Unfortunately, I had to drop out of the antho due to time constraints and was left with a half-finished story about a vampire on a spaceship, heading to a colony on a planet.

I think it is a neat idea, and was thinking of finishing it. I set in the same world as my book Starlander's Myth, which has a griffon-shifter widow. This is set in space western, cousin of steampunk type world. So we're talking some wild mix of sub-genres.

(I really think this cover needs a space ship in the background!)

Of course, there is the whole marketing question. The keywords would be all over the place. Would it attract any readers? Should I follow my muse or try to be practical?

It would be romance, of course, and probably pretty steamy.

I'm looking forward to the antho a friend is putting together.

Anyone else working on something mixed-genre? Or not working on one? 

I guess my real dilemma is the balance between the muse and the market. I don't think that will be settled anytime soon.
