What a Novella concept

I'm working on a way to resolve my tendency to write these grand epic stories, and the need to actually put out work more frequently.  

The current scheme that popped into my head is to take the spine of a novel-length concept and whittle it down to a densely packed short story.  24-48 page comic. Depending on how well received the short story is, all the stuff that would have existed in a 100-200 page graphic novel can be written as one–shot stories that flesh out the world the main story takes place in.  

Not a novel concept.  It's pretty much what Top Cow is doing with Pilot Season, but it will be an interesting exercise to reformat some of my existing ideas into this structure.
