Napoleon isn't dictating terms to Hungary, the only clause would be an alliance with France.
Was Napoleon not dictating terms to Warsaw when he setup a state totally dependent upon France? One which bore tremendous financial obligations and was forced to contribute men and materials to France. One that had an administration explicitly modeled on French lines. This was sort of the French modus operandi especially under Napoleon. The only states that didn't end up this way were ones like Bavaria that already existed and were merely allying with France, that is ones that had continuity of leadership.
While Hungary already existed it didn't exist as an independent state. Maybe I'm wrong on this and maybe the thread title of Napoleonic Hungary is biasing me to think this way but at least to my mind it won't be as simple as flipping a switch, saying Austria is defeated Hungary is now independent and a by the way a friend of France. And so once the French get involved I think it will be down the slippery slope to dependent satellite state rather quickly.
If Napoleon merely wanted to make states French allies he could have put some Italian in charge of Naples when he kicked the Bourbons out and then let them run the place on their own. Instead he put a Bonaparte on the throne, followed by Murat, with orders to introduce a French administration, French legal code, the whole Napoleonic package. And of course said state had to make substantial contributions to the French war effort. When Murat attempted to moderate some aspects of the Napoleonic code to fit a Neapolitan context Napoleon made clear compromise was not an option. So it just seems out of character that the French would go through the trouble of crushing Austria, liberating Hungary and installing a pro-French ruler only to say 'ok now you can pretty much do whatever you want and run the country however you want so long as you just stay on good terms with the France.' It seems more likely that a new Napoleonic Hungary would be built from the ground up, or at least the French would try to do so.
