Easy? No. But you can make the changes in each function as you use them and submit the changes as a pull request so they get integrated into the main trunk.
Part of the heritage of OpenCV is that it was once all C code. So it lacks a uniform use of typedefs or templates, such as the size_t you're familiar with from the C++ STL. So most people going along just assumed that int will be big enough.
Also, those are really big images.
