I wouldn't hate it if Ed Warinner was promoted to OC.  I have always been a promote from within type person, so this wouldn't bother me in the slightest.  With that said, Urbs does love him some Kenny "Smooth Jazz" Guiton, and has said many times he would be a fantastic coach someday, why not now to mentor and coach the QB's?  I wouldn't hate that at all.  Obviously, no previous coaching experience but doesn't his time as the Buckeyes gunslinger uniquely qualify him?
