I have tried this approach of finding problems and solved them.
I have done a massive code cleanup, abstracting out huge code that made it extremely readable and maintainable etc but such problems are never a problem to the upper management. For them these are red flags and a pain that they fear will cause regression and extra efforts to every other team.
So it entirely depends on the area that you solve the problem.
Also, it depends on the organization that you are working with. Especially the WITCH one's rarely care for code quality.
