I doubt it - But we've only been on the 8 division format for 16 years or so. From the looks of it, the NFC West and NFC South both did it in a span of about 11 years - going with the current 4 teams back - but those spans overlapped the old division formats with 5 teams per (with SEA in the AFC, etc) - so it wouldn't really count.
