There is a problem with this idea already.
We're not giving outbound links. If there is a site covering a topic worth discussion, we'll cover the same topic ourselves. That may take time but in we link to one web site of ours, not someody else's. Mind you we're not copying content; we're pretty good in our niche and can do a writeup on any reasonably relevant topic. For a not relevant topic, we just do not link at all.
Considering the above, whatever "flow"-link system is used, still I see it only leads to more domains. I have certain evidence in our niche the competition is doing the same way, so we get just several sets of pages/domains covering the same topics and interlinked within a set but never across the sets.
