don't understand your line of thinking. here is the ncaa site.
States that top 6 ranked conference champs make the playoffs. (they will change this as the pac 12 will no longer exist).
That means highest ranked g5 champ is in. they earned it. No pity involved.
If you looked at the teams that would be currently in and the conferences they will be in next year then you would have 5 SEC teams, 5 Big 10 teams, 1 ACC team and Liberty.
Of course they would have to knock out either a big 10 or sec team to get a big 12 team in there. So much for power 4.....lol
I get that the sec and big 10 will dominate playoff members and there might even be people screaming that it's unfair that a 9-4 oklahoma state gets in over a 10-2 ole miss but that's the way it is until they expand again.
I could see the big 10 and sec splitting off but I don't think the crumbs they throw to g5 (or even acc and big 12) will cause that to happen.
