Answer 1

Layout can be changed via themes:

Controllers via controllerMap:

With models will be more difficult. The extension does not use dependency injection, therefore, as already mentioned, its own fork with all the consequences.

Answer 2

The contents of the vendor folder cannot be touched, they are ruled by the composer.
Your task is not uncommon. Take the repository and fork it for yourself, make any edits and change the extension connection in composer.json accordingly. But you need to understand that in this case you lose extension updates in the future.

Answer 3

Isn't it possible to inherit from the current class and change what you need?
