The same (old) win/loss rules apply within your division. You have to beat more teams in your division than any other team. If you look at the home division schedules as the one that counts the most, you can never have that dilemma. The best team in the West will still play the best team in the East.
The old rules with divisions was overall sec record, no delineation of specifically vs division record. If only division record matters go to a 7 game conference schedule because those other games are in no meaningful way different than any out of conference game.
THAT IS MY POINT... My schedule is a 2 Division SEC Conference with a Championship Game. That works with the same exact rules and format as before... before Sankey killed the 2 division system. The only thing that changes (the only difference) is the teams (four teams at a time) in each division rotate from division to division. And they return in the 4th year making it a 3-year rotation. I made an 8 and 9 SEC schedule game schedule for the Gators in all 3 years. And someone mentioned if we had, say... the west division champs with 3 losses, and they play the winner of the east that is undefeated. There could still be 2 or 3 other team in the east that are better than the west champs... but how often did that scenario every play out when we had 2 divisions in the past? Regardless of the divisions I don't remember if that ever happened.
It's really not worth the debate but with divisions every SEC game counted, not just vs division, so your proposal is different. As far as the scenario... 95, 96, 98, 01, 02, 03, 05, 10 all had 2 teams in 1 division with better conference record than the best from the other. There was a stetch where the East was considered better, then with the rise of Saban Bama that flipped and the West was clearly better for a decade + until Kirby. Just look at which division the national champ came from starting in 92. West Bama 92 East UF 96 East UT 98 West LSU 03 East UF 06 West LSU 07 East UF 08 West Bama 09 West AU 10 West Bama 11 West Bama 12 West Bama 15 West Bama 17 West LSU 19 West Bama 20 East UGA 21 East UGA 22 I like your setup, but I just don't think the SECCG is goal #1 anymore. Even more so with a 9 game conference schedule. Up until last year you pretty much had to be in and win that game to be in position to win the NC. OSU wasn't even in the Big Ten title game. They got a week off to get healthy and prep and took UT behind the woodshed.
