Delay the Seven Years War

Is it possible and how? Perhaps a strong French victory in the war of Austrian succession makes Britain rethink their plans? A change in British politics and they try to find some more allies than just Prussia and forces Frederick to hold off his invasion? Anything?
 
Id Louis XV had not been a proud idiot, France would have retained the austrian netherlands at the end of the war of austrian succession. Ans by doing so, ut would have detered Britain from starting war again as soon as 1754.
