AHC: All of Empress Matilda's sons become King of England

Your challenge, should you choose to accept it, is to find a way for not just Henry II Curtmantle, but his younger brothers, Geoffrey and William (both of whom died before Henry without wives or issue IOTL), to become King of England.

Any thoughts?
 
To what degree to we determine Kingship? You could have Henry ruling parts of England in pretense from the continent, die on the ship over, and have one of his brothers finish the job. Then said brother can die and the other one can become King
