How about the Super Etendard really was super, i.e. higher performance than jaguar, perhaps pretty much a French Super Tiger, and as such was a viable replacement for Frances Crusaders? Increased production run plus maybe more exports of this mach 1.7-2, slightly multi-role fighter.
Maybe as well as more power it could also have had a blown wing, or other high lift features, making operation off modernised Colossus and Majestic class carriers truly viable.
One of my books stated that the US was looking at recommissioning four modernised Essex class carriers in the 80s as part of Lehmans 600 ship navy, a reason stated for this not going forward was the lack of a suitable modern combat aircraft to fly from them. An Americanised Super Etendard (a genuine Skyhawk, Crusader and Corsair replacement) bought to fly from the recommissioned Essex's as well as from a new generation of CVS procured to supplement and replace them.
