Do you guys seriously think Kenny will come back to manage Derry when his tenure at Ireland ends? He lives in Blackrock LH for start, no way he'll up sticks again and move for a LOI club, I don't think he will make a return to Oriel Park (maybe in 10 years !) but clearly his next move after Ireland will be a club abroad, (not England or Scot), his options will be continent europe (mid leagues) or US (mid leagues again) IMO, both options not to be sniffed at mind, both will pay very well.
All that said, I don't think Higgins is the right man to lead Derry forward, I'd put him with his fellow mgt team colleague at DFC Vinny Perth, both are good coaches, not what I would consider as great managers.
