You're aware that there's more to the galaxy than clone soldiers, right? Palpatine had the adoration and willful obedience of the people (most of 'em). Anakin is just some shmuck. The galactic masses have no cause to believe in his leadership. And given that, again, he's an idiot, he'll screw up whatever he does try. Palatine also inherited a millennium's worth of knowledge, finances, resources, and power from the Sith Order. Anakin's got f*ck all in that regard. No charisma, no charm, no smarts, no leadership position, no capability. If Palaptine died circa 19 BBY, then Anakin's brief tenure under him as a Sith was in the role of glorified assassin. That, nor any of his other lack of attributes, is the characteristic trait of the leader of a massive galactic community.
At that stage, there would be no "inheriting the Empire". That new and young, such a fragile state would collapse quickly without Palpatine holding it together. The upper echelons of political and military power (who weren't clones) would scramble for whatever they could--fragmenting whatever "imperial power" there was that early on. And the drive to re-establish a Republic would be very strong in lieu of it all. The Empire wouldn't exist beyond Palpatine, and as we've seen in the EU, even after it was consolidated 24 years later, it still fractured quickly after Palpatine's death. And it was only he that could re-establish it again when he was Reborn. And then it collapsed again when he died. Again. Palpatine was the Empire. Vader was nothing. [/QUOTE

Anakin had no political mandate. If he were to kill the emperor at the end of RotS, the Senate would retake power and Anakin would, at a minimum, be court marshalled, and at the most, be hunted down and killed by the clones.
In the OT years, he was too busy keeping Palpatine's minions in check. If Palpatine were to die unexpectedly (and Vader survived), there would still be a power vacuum. While Vader was a high ranking military official at this point, he still doesn't have much of a political mandate. The common people would see the Emperor's death as a lapse in control, and the rebels (or pro-Republic movement) could possibly gain ground.
The military would splinter and there would be basically warlords vying for control.
Interestingly enough though, this would probably be a more difficult environment for the Rebels to deal with. Having many decentralized enemies would be difficult to manage. Assuming the Rebels would be run by ex-Senators (since the Senate has been dissolved), these ex-Senators would have to convince the regional governors to support them.
Ultimately though, the Rebublic would have probably been reformed.
