Converting Legacy Code to MVC

I am currently converting a legacy 50KLOC Java application to MVC. After a few days of analysis, I concluded that the View-Controller (VC) part is quite complex and I should first focus on isolating the model classes. When isolating them, I also remove dependies to VC classes. That way, I will be able to have independent, resusable model code in a fairly short amount of time. If time runs out before I finish the VC part, I will still have accomplished something.
