Those are some well made and logical points you make, Channel72. I’m sold!
One thing that would require some explaining is the sheer volume of material needed: we know that DSI required a mass effort, and other Imperial projects shelved in favour of building that, so this much larger DSII would require even more effort, slave or prisoner workforces, mining for components and so on.
On the other hand, there is no Imperial Senate around to placate and swerve around, like there was for DSI. Nobody in the way asking questions or or investigating just why there are so many prisoners or slaves working on certain projects for this. Or why resources and efforts from planets and systems across the galaxy are being diverted into “black holes” or classified projects.
I agree with Servii above, in that the more we have seen on DSI, the more abrupt it feels DSII was built in comparison.
I’d love to see something along those explained, in a short feature or animated anthology episode; something like in “Tales Of The Jedi” if that series is going to expand beyond doing Ahsoka-themed and Dooku-backstory episodes.
Or even in a one-off Disney+ film on the building of DSII, with the Bothans, having the Rebels and Imperial POVs, the Emperor’s plan being implemented by his underlings, along with his deception that the superlaser wasn’t ready and so on.
