Yes, sure. You don’t even need to restart to load additional Python modules. See source code of extension wizard for details.

Also, you can have a look at how the [modules panel](https://github.com/Slicer/Slicer/search?q=Additional+module+paths&unscoped_q=Additional+module+paths) handles [directory paths.](https://github.com/Slicer/Slicer/blob/9a1c335d8b6896f3deabc550721a5deca07247b6/Base/QTGUI/qSlicerDirectoryListView.h#L34). And `slicer.util.restart()`.
