They would continue to rely on CdeG. The financial and technical reasons that led to the scrapping of plans:-
Firstly for a second of class. And then
For a QEC based PA2. And finally
For a second carrier at all.
Macron (elected as Mr Fixit) then becomes a really unpopular President, so much so, that his re-election prospects are in some considerable doubt, comes up with a “carrier plan”! It will be for his successors to decide and the likelihood of just continuing with CdeG and pushing the decision further into the long grass may be far too tempting for the President of a country that is still beset by economic concerns and taxation/social unrest.
The French, like us NEED 2 x Carriers, but have accepted possession of only 1, for around 20 years already. There would really have to be a political Tsunami to justify the sort of expenditure required to the French population, with any hope of making it stick.
Of course, if Macron was more popular .......... !
It is a sad state to be in, one in which France is not alone ..... Namely for democratically elected governments to be unwilling or unable to provide adequate defences for their people.
