The idea, suggested by some, that the AQ conferences would ever agree to eliminate AQ bids ignores the fact that this is virtually impossible to do. 5 of the 6 AQ conferences already have tie-ins with BCS bowls. There is no way to run the thing without honoring those tie-ins. The only conference that can be denied an AQ bid is the Big East & that could happen in this round - especially since Rutgers is the only school remaining in the Big Eat from the original group that was included among the AQ conferences when the BCS was formed.
The other factor in eliminating an AQ bid is that "undeserving" schools from the Big East & ACC are not the only ones who would face elimination in a bad year. The other conferences have at times also been in the same boat. Even if the Cotton Bowl were added as a 5th bowl, raising the total of partipants to 12, here are AQ conference champions who have finished outside the top 12 in BCS history:
1999/2000 - #24 Stanford (Pac Ten)
2000/2001 - #13 Purdue (Big Ten)
2001/2002 - #13 LSU (SEC)
2002/2003 - #14 Florida State (ACC)
2004/2005 - #13 Michigan (Big Ten)
2005/2006 - #22 Florida State (ACC)
2006/2007 - #14 Wake forest (ACC)
2007/2008 - #13 Illinois (Big Ten)
2008/2009 - #19 Virginia Tech (ACC)
2010/2011 - #13 Virginia Tech (ACC)
2011/2012 - #15 Michigan state (Big Ten)
So, even with the Big East excluded, almost every year there is a representative of the other conferences who has gained access to the BCS & has finished outside the top 12. If this year continues as the rankings stand today, the Big Ten champ will finish outside the top 12 for the 3rd time. There is no way that these conferences are going to agree to a system that excludes their champion even once - much less multiple times.
Also worth noting that in some of these cases, you are including schools on the list that were upset winners of a conference championship game where the conference also sent a top 10 school to the BCS in addition to the school listed above. And your list seems to be missing all the Big East times.
