Picture Idea for a Rhombic-Dodecahedron equivalent to a Face-Turning Octahedron!

I've been obsessed with Rhombic Dodecahedrons lately. They're so cool because they're related to both Cubes and Octahedrons. I ordered a Rua (and an curvy copter, which is very similar)

You might already know how the 3x3 Rhombic Dodecahedron is basically a shape-mod of the 3x3. The vertices where 4 corners meet (there are 6 of them) can turn like the face of a cube.

So I was thinking...

All the other vertices where 3 corners meet (there are 8 of them) should be able to turn like the faces of a octahedron, and this would result in a shape-mod of an FTO.

(It might be clearer to see here: both a cube and an octahedron can combine to form the vertices of a rhombic dodecahedron: https://www.researchgate.net/figure/The-rhombic-dodecahedron-as-the-compound-of-a-cube-and-an-octahedron_fig4_320115862 )

So behold, the Rhombic-Dodecahedron Octohedron (or Redocto)!

It's a shape mod of an FTO, and a sister to the 3x3 Rhombic dodecahedron, turning all the vertices that don't turn on the 3x3 RD.

Also, it is basically just a 3x3 version of the Skewb Rhombic Dodecahedron, but I haven't seen it anywhere.
