I honestly think that is the plan. I have read on some ACC boards that Clemson and/or FSU would be interested in joining if ND were to hop on board. I would be thrilled if we added Miami, NC, ND and one of Clemson/FSU.
I know some will throw around the fact that Clemson and FSU aren't AAU schools but honestly, that won't stop the B1G from adding those 2 if they want in.
