What if Buu's body instanly broke the shield and he was able to absorb Vegito. "Ahhhhhhhhhhhhh, This power manifest in me. I am truly the strongest being in the universe. There is no one to opposed me," just then he got a headache. The Gohan within him had awaken. Gohan took control seperating the Buu, into two. Although he lost alot of power, he was still way stronger than Gohan Buu, who was now good, since being under Gohan's control. Gohan Buu, although alot weaker than Vegito Buu, punched him hard enough to make him regurgitate Piccolo Buu.
