That may be what the schools want, but it will never be successful. People aren't going to pay $10 per game. People here don't even want to pay $10 to sit in the stands.
I think the closest comparable model for an ACC-only streaming subscription would be MLB.tv which was originally priced at $130 for the 2021 season.
If that were ever to happen it would be Armageddon for college sports, because the money would be drastically reduced.
