I've worked on some bad codebases. You can convert a little bit at a time, treating the remainder of the codebase as a large library with a poorly factored interface. You absolutely will need unit test coverage at the boundary, which will probably exist for several years.
Honestly, I can't say how it would work if I was using a java code base that consistently applied these kinds of ideas. You may be right, but at this point I have hard time believing.
