WI: Henry of Anjou dies before Stephen of Blois?

I hope this doesn't get me into trouble.

I've just come back to this idea, and have come up with a short timeline for the short-term effects of Henry's death.

1. Henry dies crossing the Channel. His brother, Geoffrey, inherits Anjou, Maine and Normandy, but this claim is contested by Eleanor of Aquitaine, who is pregnant with Henry's child. Geoffrey declares his right to succeed by proximity of blood and/or declares Eleanor's child a bastard. He then turns his attention to Brittany, planning to make it his vassal or preferably gain it through marriage.

2. Either beaten or biding her time, Eleanor returns to Aquitaine, where she gives birth to Henry's son, William. She later remarries to Raymond V, Count of Toulouse, and forms a betrothal alliance with Burgundy - betrothing her eldest son, William, to Odo II's youngest daughter, Mahaut.

3. Stephen still dies in 1154, but Eustace becomes King of England. As part of a plan to reconquer Normandy, he marries off his sister, Marie, to Conan, heir to the Duchy of Brittany. Duchess Bertha also arranges a betrothal between her eldest daughter, Constance, and the young King of Scotland, Malcolm IV. She is shipped off to Scotland before Geoffrey can get to her, so he instead kidnaps Bertha's younger daughter, Enoguen.

4. Eventually, Geoffrey is either killed or deposed without issue, while Enoguen returns to the Abbey of Saint Sulpice. Anjou and Maine pass to his last brother, William, who is married either to Adela of Champagne (OTL third wife of Louis VII or France and mother of Philip II Augustus) or Matilda of Burgundy (sister of Odo II, Duke of Burgundy). Normandy is left up in the air...

Any thoughts?
 
Here is my Idea, Louis tries to impregnate Eleanor of Aquitaine again to prevent a divorce in 1151, since Alice is born in 1150 IOTL, since Eleanor is in an affair with Henry, the son is with a doubtful paternity but he will claim that he is his son..regardless.

Henry is possibly imprisoned by Louis VII due to the affair.
 
Proximity was more upheld in Normandy than Anjou so Geoffrey will likely hold Normandy and Maine in his own right but might have to settle for Regency of Anjou and Touraine until he strongarms the barons there.
Someone should be courting an alliance with Flanders. Phillip was cocount with his crusading father from c1157 and married the heiress of Vermandois in 59. As Count of Artois he's Eustace's liegelord for Boulogne. The Count of Vermandois also happens to be married to Eleanor's sister Petronilla.
I suspect Phillip will end up the mediator between all the parties.
