Really is most likely that if 2 teams come from the North, it is the 3 and 6 seeds. That is because the East is so terrible, the divisional winner will certainly be the 4 and the West is so good with San Fran and Seattle, it will be 2 and 5.
Green Bay really can't get to 2 and also lose to the Bears. And the Bears can't get in without beating Green Bay.
The only mathematical way would be either San Fran or Seattle losing out to get to 10-6 and being the 6 seed which moves the Bears to 5. Green Bay can't be 5, they would lose on tiebreakers to both West teams and be out of the playoffs all together lol.
