Idea: Backstory Contest

I had this idea today when working on some backstory for an age of mine:
What about a backstory contest?
The concept:
Contestants take an already released Age (does not need to be an Age of their own), and write a short/long story around that age. The story has to respect established Canon for that age, and established D'ni canon, but beyond that, no restrictions apply.
Judging categories could be:
- how well does it fit the age
- how compelling is the story
- quality of the backstory used
- support items (drawings, separate notes, items, etc....)
Ok, clearly I'm not qualified to propose judging categories for stories
Anyone got ideas/opinions?
