First off let me premise a few things:

1. I don't frequent forum boards enough to see if my dumb questions have already been answered and buried by posts, usually because there are rules against repeat questions. This causes me to never ask, even when I can't find anything because "you're probably not looking hard enough", so I apologize if this has been answered and I just can't find it.
2. I am not intending to commit, condone, or cause any form of piracy. Any action I take as a result of any answers I receive will be done so to the legal-est of my possibilities, no matter how cumbersome.
3. For all intents and purposes, feel free to call out my lack of knowledge on the matter in any rule abiding way you see fit.

Now onto the question:
I have been looking into r/SwitchHaxing because to this day the idea of affordable, portable, and moddable Skyrim all-in-one never ceases to excite me, when I noticed multiple claims that the files to the game are mostly the same, with the exception of Hyrule.esm, and that mod conversion is super easy. I then remembered the time someone uploaded a torrent of the Nuka-World DLC for Fallout 4 to the Nexus as a Mod. This got me thinking: "In theory, if I could extract Hyrule.esm from Switch Edition, could I install it like a mod to Skyrim Classic?"
Now obviously, I would not be allowed to distribute anything, but I might be tempted to, oh, buy the supposed "New Switch" coming next year, and use my old one as a Homebrew Guinea Pig, with this being a potential personal use only project.
So, yes? No? Maybe so? "n00b y r u askin this here lol gtfo"?
Thanks in advance, and regardless I hope you have a nice day.
