It's possible, just use the
PyPRP importer.
Beware, though: importing the whole Age (.age file) will take forever, and eat up a gig or two of RAM. It's best to import it as separate PRPs: save each scene into its own blender file, reload the default scene, and import the next one. You can merge them after that anyway.
Keep in mind that this tool is limited and skips lots of data, so you won't be able to re-export the Age after you imported it.
