It's possible. But as the other commenter says, it'd likely be much more effort than it is in emacs just because of how the model the editors are built on differ.
You can definitely accomplish something like this in VSCode and I would strongly encourage any student to explore customizing their own tools and workflow.
The main difference is that VSCode “extensions” (which in most respects are very much like emacs modes) are usually written in TypeScript rather than elisp. In fact there’s a guy called Steve Yegge who has blogged a bunch about an effort to make it possible to extend Emacs with JavaScript, so there’s lots of precedent for the analogy.

You should exercise your own programming muscles and write your own IDE, Operating system , cpu architecture, fabrication process and electricity generation for yourself, rather than relying on others to do everything for you.
