It might just be done.
I've deleted a few scenes near the start that I thought might slow the action down. And I've added an action scene to a later part and tweaked a different action scene to make it better. I'll know when the outline feels "right." Then it'll be time to start the draft.
My goal is to publish at least the first three books of this series in 2017. That's in addition to the three books of the Free Space trilogy. So at least six total for the calendar year.
