Here is the alternative I think is more likely for 2 team divisions so the NFL can promote more games as meaningful and more teams as relevant every year:

AFC New York:
Buffalo
NY Jets

AFC Atlantic:
Miami
New England

AFC Southeast:
Jacksonville
Houston

AFC Central:
Indianapolis
Tennessee

AFC Ohio:
Cleveland
Cincinnati

AFC Colonial:
Pittsburgh
Baltimore

AFC Southwest:
LA Chargers
Las Vegas

AFC Great Plains:
Kansas City
Denver

NFC Lone Star:
Dallas (Cowboys guaranteed a playoff game every year for ratings).

NFC East:
Washington
Philadelphia
NY Giants

NFC Gulf South:
New Orleans
Tampa Bay

NFC Southeast:
Atlanta
Carolina

NFC North:
Minnesota
Green Bay

NFC Rust Belt:
Detroit
Chicago

NFC Northwest:
Seattle
San Francisco

NFC Southwest:
Arizona
LA Rams
