Victory-class Star Destroyers would work great though, as they were still used a lot by the Empire. N-1s aren't used a whole lot by the Rebel Alliance, so I'd say it's more questionable. An edit doesn't have to agree with the EU necessarily, but if it does not then it is non-canon. And with something as minor as ships, you might as well stick to canon, right? I don't see how anyone could find a problem with adding, say, an Imperial interdictor as opposed to an ARC-170. If you don't know better, it's all the same to you, no?
And I have never seen any issue with the planet below the Death Star in Revisited. No conflicts.
