I've posted about this on a few occasions, but if the G5s ever decided to take things into their own hands and create the 6th Power Conference there isn't anything the P5s could do about it. If they actually followed through with it, I'd want BYU to join:

"Everyone focuses on what the G5's don't have, let's focus for a minute on what they do have:

-An automatic bid to a New Year's Six bowl game
-$90+ million in annual College Football Playoff Revenue
-Several networks still eager to broadcast college football

Now, if these assets were to be split among a single conference instead of 60+ teams, you know what that looks like? A Power Conference.

If the G5s would start thinking bigger than their measly $1.5 million per team payout, they could use their newfound "autonomy" to create a sixth Power Conference and the P5's couldn't do a thing about it. And here's how they could do it:

-5 G5 football-only conferences (1 Premier, 4 regional West/Central/North/South)
-NY6 Bid goes to Premier Conference winner
-CFP money is divided among Premier Conference members only
-TV deal is negotiated for Premier Conference (The old Big East was offered $100 million/yr, this conference could easily get something similar, if not more, especially with a Championship game)
-The regional conferences negotiate their TV deals as a whole (they would have value because of flexibility of having games nationwide, and there would be good value in each regional championship game being a play-in game for Premier conference membership)
-Premier Conference membership can fluctuate between 9 and 18
-Teams with a 4 year average rating in the top half of CFB (Top 64), teams that finish in the top half of the premier conference, and the previous year's regional conference champs are admitted to the premier conference for the following season.
-By eliminating bad teams from the Premier conference, the champ actually has a shot at the CFP due to SOS by not having to play bad teams in-conference
-All other sports go to traditional regional conferences that actually make sense and minimize travel costs (Tulsa & Temple in the same basketball conference? Nope.)

The G5's could do all of this without needing anything from the P5's, but it would involve sacrifice and investment in their own programs, which too many aren't willing to do."
