reften, it doesn't matter if region 4 or 5 or any other region want to reunite with D2. The D2 schools are the ones that split. There are still a few private schools(around a dozen or so like Boyd, Lispscomb, Chatt Christian, Notre Dame to name a few) in D1. Tell all the other D2 schools to come back to D1. Then you can raise money for the new venue. Problem solved.
