won't happen, your average shinobi moves so fast that the stormtroopers won't even perceive them. Add Killer Bee's Bijuudama (or whatever the name of that attack is), Naruto's Rasengans, Sasuke's Susanoo oneshotting them all and Itachi putting everyone in a genjutsu and using his own Susanoo, add all the other elites and Naruto verse stomps. Hell, Toneri used an attack that cut in half the moon, he could cut the whole fleet like butter. They wouldn't even land on the planet
Death star destroys, Naruto world.
SIdious unleashes a force storm, on the planet.
SIdious possesses, and drains the naruto verse.
GE sends waves of star destroyers, capable of tanking continental level attacks,
Completely leveling the planets surface.
The GE drop a quantum bomb on the planet, or something like it, destroying thousands of kilometers of the planet, literally screwing the planet over.
Sure naruto/toneri etc will destroy a few star destroyers, but they are screwed in general tbh.
sure about what? Toneri cutting the moon? Yes, it happened in the movie "The last". Also to answer to another comment, sidious is getting blitzed by the top tiers. And even if his lightning landed Naruto tanked attacks from the guy I mentioned above who was cutting moons in half, lightning will do shit to him. But not only him, Pain was getting punched and thrown around by Naruto who had almost tranformed into the nine tails, but still he didn't receive any particular damage. Hell, Itachi himself tanked Sasuke's Kirin, which is made of lightning, with V3 Susanoo, and Kirin destroyed the whole Uchiha Hideout, don't remember Sid destroying while buildings with his lightning
Oh right, forgot about Force storms. Well, if he isn't killed before he can summon one then empire may win. Still DE Palpatine era empire didn't have the Death Star so if he is killed then imperials are stomped
The Allied Shinobi Forces had 80,000 troops and that was like all the major countries. Even assuming composite eras, an empire that spans a galaxy should outnumber them by a lot. The majority of ninja can't fight in space and narutoverse has no defense against the Death Star or even orbital bombardment (see Madara vs everyone). Maybe they can win a war of attrition with Edo Tensei.
