A difficult proposition.
We are not talking "fighting the French" since this does not mean anything then, because politics are framed in terms of feudal allegiances, we are talking fighting the King, the Crown. So when you say "with crusader help", you're not talking a rebellion by a troublesome vassal like Charles the Bold of Burgundy did IOTL, you are implying a Crusade against the King of France. Lashing out at Cathars is one thing, waging war against one of the most powerful, in theory at least, sovereigns of Christian Europe, quite another.
Then no ruler there really wishes for "independence". The Raimondines after being expelled from Toulouse can only survive as a staunch ally of the Capetian crown in the South, against either the Welfs of the Kingdom of Arles, the Aragonese and the Aquitaine, lest they be eaten up by their Trancavel vassals in Septimania or by the House of Poitiers.
And the Dukes of Aquitaine stand to lose lot of land to the House of Anjou (our OTL Plantagenet), ever keen to expand their domains in the Loire Valley at the expense of Aquitaine.
The worst thing that can happens is rebellions if like in England IOTL, the King policies were encroaching on their vassals' privileges, like the Capetian-Plantagenet or the Burgundian wars, rebellions that could at best lead to reinforcement of said privileges. The Dukes of Aquitaine, if very lucky, meaning Welf Imperial support and a total collapse of the Capetians in the South, could think of reneging on their homage lige and restoring the centuries long dead kingdom of Aquitaine, but then, that is not Languedoc, that is Aquitaine.
So, independence? At the time, you really had only the historical core of Swiss cantons who did that even though that was only recognized in 1648 treaties of Westphalia, the Scots and later the Swedes, but only to restore their independence, not to declare it, or the United Provinces
