For all practical purposes that is what they will end up doing. The winners of those conference championship games, providing they don't have too many losses will end up being odds on favorites to get selected by the committee. I'd say the odds of one conference having two representatives is going to be less. Teams will essentially be playing their first playoff game in their conference championship. The thing is if a team wins an upset game in the conference championship (the lower ranked team with maybe two or more losses already) they won't get selected into the final 4 and shouldn't be if there is another team more worthy.
