Bakugo might be able to stop the attack. He probably will as otherwise he’ll probably die.
But he will fail in preventing AFO from reaching Shigaraki. That has to happen because ultimately, AFO is the main villain and not Shigaraki.

My theory:
-Bakugo stops the attack and overpowers AFO, turning him into a baby.
-Baby AFO transfers his quirks to All Might. Since All Might was born quirkless, he is capable of taking AFO and not dying.
- using All Might’s body, AFO reaches Shigaraki and takes over his mind
