Easy way to win this battle for the Sith: Have part of the main fleet engage Imperial Forces in the skies over some random important planet. Let them get mostly butchered.
Send Naga Sadow to the sun in the Coruscanti system. Detonate the sucker. Wash, rinse, and repeat.
Even easier if they are pushed on the defensive from the start. The fewer they own the easier it will be to take out the Empire. Just lure the massive Imperial fleets into traps with Sadow around and bam you have the end of one of the imperial fleets.
Technology is nice, but even technology can't give you victory against living gods.
Was Aleema Keto a living god because she, too, could use the technology in Sadow's ship directed by her Force powers to manipulate stars?
I think we overestimate the Sith a bit, but I also think it would be a hell of a fight. It depends quite a lot on how many times the Sith can lure the Empire with Sadow's ship.
No, Aleema was a weakling compared to Ragnos, Sadow, Kun, Kressh, et cetera. But Ragnos is a force god, possibly the most powerful Sith ever to exist, aside from Nihilus. The other Sith Lords are veritable gods too.
Think about it, if Ragnos and his demigog of Sith Lords attacked at once they would be able to obliterate the fleets by sheer power. So they don't really need the ship to win. The ship helps, by a very large margin, but they could still win.

And the point exists that if the ancient Sith had technology that could manipulate Force energy of even lower level users such as Aleema and make stars go nova this entire fight does not bode well for the Empire.
Plus Sidious and Vader's position would be sorely undermined. There can only be two Sith in the Post-Ruusan galaxy. When god knows how many Sith Lords (who's weakest members could crush Sidious and Vader like a bug) start popping up, the Empire might start to fragment under the pressure. The fleet admirals would lose confidence in Vader's power. Some of them would probably seceed and turn renegade.
Imperial power is somewhat based upon a "doctrine of terror." If they see someone like Vader, a relatively fear-inducing person getting squashed like an insect, then their morale with plummet.
Plus, psychologically, if the Sith sent an army into battle, the Empire's troops, seeing seven foot tall men butchering people and then smashing their heads in with Sith magic will have an extremely adverse effect on the psychology of the troops.
