Sounds like it could happen, as a consultant.
Found this little blurb at JS:
"Marty Schottenheimer, who gave McCarthy his first job in pro coaching, might figure in Green Bay this season in a consulting role.
"I think that's something that could be visited down the road," McCarthy said. "He's the best football coach I've ever had the opportunity to work with."
Schottenheimer, 63, was fired last week as coach of the San Diego Chargers."
