My dream scenario is this
ND/WF Orange
UM/Louisville Sugar
OU/ Boise St Fiesta
LSU / USC Rose
That would actually make some sense if the Bowls agree to it. Especially sending ND to the the Orange to help with any trouble Wake MIGHT have on bringing the numbers
LSU's defense is fierce.
The chances of LSU going to the Rose Bowl over Michigan is roughly zero.
Problem with that is, I believe the Sugar's tie-in with the SEC means they have to take Florida or LSU, whichever one is available.
