Book cover design prize?

Hi all, your nearly-absentee-owner Jeff here with a quick question.

I'm thinking of running a Facebook contest designed to get more likes, increase the pool of people using HeroMachine beyond the traditional, and increase incoming links. The idea would be to have people use HM3 to make a portrait of a character from a novel, novella, or short story collection they have written. The winner would get to have a cover for that product designed and illustrated by yours truly, much like I've done for Ian Thomas Healy's "Just Cause" books.

Is that something you think would be of interest?

I imagine even if you haven't written a book yourself, it might be fun to have one for a book idea you've had.

Anyway, I'm throwing it open to comment, please let me know what you think (good, bad, or indifferent).
