Never mind, I have been using version 9.4.2. There are a couple of extra features implemented in the newest versions that will help me, e.g., there is a PETScWrappers::MatrixBase constructor that takes a Mat as input (https://github.com/dealii/dealii/commit/97911ba3839d7a06c3fb0cd06f7574ea0849103b). Thanks to the developers :)
