Need help to repair Battle Blade Bumblebee

My Bumblebee broke the ball joint peg that holds the head.
So now,I have the peg still in the head and rest of the body.



Glue would be too fragile to use if intend to transform him again.I Though to use a very thin nail to link the joint back to the body,maybe even heat it up a little to get inside of plastic body better,but dont know if it is a good idea.
I'm open to suggestions.
