No chance.
Harbaugh was a god in Michigan folklore, a successful NFL quarterback and as a coach he won big at San Diego and Stanford, while reaching a Super Bowl with San Francisco.
He was their white whale and pie-in-the-sky, dream head coach for eons—and they finally landed him, expected him to win big and knew there was no Plan B if they didn't—so they rode it out and gave him time to get it right, as his name is literally synonymous with Wolverines football.
Mario Cristobal was an offensive lineman on two national champion caliber Miami teams way back in the day—he was never a superstar; just hard working guy in the trenches—and he's cut his teeth as an assistant under some solid coaches (Davis, Schiano, Saban) while getting his feet wet at FIU and doing some good things at Oregon.
He's a very logical hire for the Hurricanes as he has that same "Miami-bred", "understands the program" thing that Diaz was supposed to understand—as well as being a tireless recruiter—but in no way does his name carry the same weight within this program as the name Jim Harbaugh does at Michigan.
Weak comparison to try and prove some point.
