Unfortunately, the Copenhagen interpretation is weaved into the very fabric of QM as it exist to this day, and it would be a huge deal if we could replace it with some other consistent theoretical framework that would not be modeled after classical physics with its notion of measurable properties.

What do you mean by that? Pilot-wave and many-worlds have EXACTLY the same predictions as the Copenhagen interpretation. It's the same theory, in the sense that the same mathematical equations, expressed differently.
