[Star Wars] How would the galaxy had turned out if the CIS had won the Clone Wars?

The main person responsible for the defeat of the CIS is the very same person that created it in the first place.

So the first question is how could they even win? Well, pretty much the only way would be if Palpatine was killed and revealed to be Sidious at the same time.

This would cause huge repercussions, as the basis of Republic law had changed radically to "Palpatine is the one leader", yet people would now know that he had tricked his way there, the system is horribly broken. So, what now?

Well, without their leaders, the CIS would now consist of more political people who want to leave the Republic as they believe that they would do better on their own, however they would likely distance themselves from Palpatine/Dooku/Grievous. 

With the senate in turmoil, everyone claiming power and the whole thing being a colossal mess, the prospect of each planet working individually - at least until they can create a new central government - would sound very appealing. The planets who joined the CIS to leave the Republic would be allowed to do so.

As for the Jedi? They would likely take a backwards seat in all this discussion and step in when it looks like violence will start - they will just keep the peace between all these people looking for power.
