I don't think there are any rules that forbid it - and you could probably get away with it without the creator knowing about it, unless someone brings it to her attention or she randomly stumbles upon it. Although, if you just want to be a good person, you could have a copyright notice at the end of the story, or you could ask Kiki-kit on DA for use of her character.
