Urban Hat€monger ?

What they should do is instead of turning Cena heel is to make him an even more obnoxious babyface.
Have him be a stickler for fair play and have him admonish other faces for cheating or attacking other wrestlers telling them a bad example for the kids watching.

Bo Dallas was doing something similar in NXT but he did heelish things as well, have Cena do that but without acting like a heel, just have his self rightousness as the heel part of his character.

That way he could be a heel and still be a hero to all his make a wish kids.
