Replace multiple objects with empties


is there a quick way to replace multiple objects with empties, keeping rotation/scale? Thanks

Maybe this helps: You can change easily the Mesh inside your Objekt with a ‘fake-empty’-mesh (here created from a cube, only 3 verts)
But this is extrem simple, not very elegant…

Thanks! I was thinking about using a single vert, but it is a workaround and I’m not so happy with it. Thanks anyway.
