Is it possible to migrate shootergame c++ project into existing blueprint blank project?

The opposite way- blueprint blank project into shootergame C++ is clear, but from C++ into blueprint is the problem. Some help?

Not easily is the answer, you’d be better off doing it the other way around.

So is it possible. How complicate can it be? 10 steps,20 steps, 100 steps?

By not easily, I mean if you don’t know how to do it already with your own knowledge it’ll be practically impossible for you to do it at all. Just copy-paste your Blueprints into ShooterGame instead? Surely that’s the easiest way?
