True, that would be a significant problem. But still, I feel like there ought to be a way to get a second OS working over windows running your custom shell but deferring to the Windows OS when it comes to the matter of running software. I guess it'd have to be more involved than that to avoid slowdown. I feel like there's bound to be a software solution too here...

I'm not sure if anyone's suggested this yet but Would it be possible to build your new UI on top of even the restrictive modern versions of windows using some sort of remote desktop app? Like, if you were to just put a Raspberry Pi or arduino between your monitor, mouse and keyboard and your desktop, you could have whatever shell you wanted installed in that that interacts with windows on its level but lets you interact with it however you configure it?
