It make sense to me. Maybe something like this? The Coastal just got even easier for Tech to win too.
Coastal-Atlantic cross rivals
Virginia Tech-Georgia Tech
Virginia-Clemson
Pittsburgh-Syracuse
Maryland-Boston College
North Carolina-NC State
Duke-Wake Forest
Miami-Florida State
If the ACC smart they'd use the change to also make sure more marquee games happened. UVA v Clemson may have history, but VT v Clemson would have TV audience.
