I probably would try a mini-season. But I like writing fanfic, and I learn and keep in practice by doing so; and I like playing in my original fic universes without necessarily knowing where the entire plot is going. It's rare I write original fic one-shots, and original fic one-shots of a particular length are what naturally do best; although if I'd done better with my one-shot mythology AU, I wouldn't have been in the redemption poll against a personal/diary style post that week. So a definite maybe :)
