#2. Why he won't: He's invested too much into Kofi Kingston already
Now here's looking at the other side of the coin from the previous point. Even if Vince McMahon wasn't a fan of putting the WWE title on Kofi Kingston in the first place, Kingston certainly earned his respect and won him over in those two months.
We often accuse Vince for having our voices fall on deaf ears (and more often than not, it's true), but in this case, we can only acknowledge and appreciate the fact that McMahon and WWE fully listened to the audience and pushed Kingston to the pinnacle of his career.

Given that he's already invested so much in Kofi Kingston, he may feel as though there's a better way to end his WWE Championship reign than by having Shane McMahon, of all people, be the one to dethrone him.
