FWIW -
SEC13 won't last but a year, maybe two. If just one year (2012), Aggies in the West. If a second year (2013), Aggies in the East. All schools would then play A&M within first two years, and the lopsidedness would be in the West the first year and in the East in the second year.
SEC14, if Mizzou = #14, put Mizzou in the EAST. See this map from the Mizzou2SEC site (see
http://mizzou2sec.com/:

It seems weird, until you realize that Mizzou isn't that far from East teams UK, Vandy, and UT. It works even better if Arky is Mizzou's permanent cross-rival, with South Carolina switching from Arky to be A&M's permanent cross-rival.
None of the current SEC division assignments would change, and none of the other cross-rivalries would have to change. Don't like that? See this:
