I was doing some thinking about the data model behind this thing in light of the master outline https://wpshowdown.wordpress.com/master-outline/ (and the way WP works) and realized that rather than trying to collect a massive amount of Pages around the home/main blog, each "Project" within the system should just be created as a new blog. That gives it its own "space" for Pages, a blog, the ability to "collect people" around that project and list participants etc.
