I don't know if the brass at Clarkson have enough brass to bring Mark back. Maybe it isn't brass they would need, it would be intelligence. The Clarkson hockey program has been fractured since he left. The admin did not look good when they did not support Mark during the framing fiasco. Now you have the current admin giving George a verbal green light and then taking his legs out at the last hour.
In my opinion, the admin could save some face by doing the right thing and at least asking Morris if he would be interested in coming back. Heck he might even accept, although he is in a better place now. However, he has been living away from his home, and his wife is about to become Judge in Massena, therefore she is not going anywhere.
It doesn't seem like Clarkson is very efficient in their hiring process, let alone exercising any sense of intelligence within the admin.
