You don't have to explain to me how you think your vision would work. I know. This is a money making scheme, and always has been for the last 20 years. Divisions with "Division Champs" is far more marketable than your version which produces a single champion for the conference at the end of the day. Division champ looks better than 4th place. This will absolutely emulate the NFL, the most profitable version of american football. There is no reason to do what you propose.
And the NCAA can't emulate the NFL.
The money for conferences and teams will be getting a spot in the 8 or 12 team playoff. The $2B from the playoff is more valuable than splitting $50-75M sixteen ways within a conference by playing a CCG series.
In a pod CCG structure, 3 of 4 teams in the conference will have lost their last game before a selection committee or computer determines the playoff teams.
Same goes for the really elite teams like Bama, Clemson and Ohio State over the last 5 years. In an 8 or 12 team playoff, it seems like they have more at risk by playing in a CCG series. Losing one of the top 4 seeds and a bye. Player injuries.
Plus I don't think University Presidents will be too keen in potential for college football teams playing 16 or 17 games (12 regular season, 2 CCG series, 2 or 3 Playoff).
