It very well could have been, there was a plan for that 0,to convert the modules into a complete space station not simply a one-off orbiter. During the space shuttle program several former astronauts put forward a program called dry centaur, the idea was it would be possible to boost the large tank into orbit and convert them slowly into a larger space station, more like something von Braun had envisioned.

I think the real problem was that the public after the moon landing simply lost interest in the space program. Von Braun had envisioned an orbiting space station, we would launch from Earth to the space station then transfer to a lunar transfer module which would launch to the Moon and then a landern would go to and from the Moon and then that lunar transfer vehicle would come back to the space station.

I had everything that you used to come out of the Huntsville rocket Center about this unfortunately when I left for college my mother threw it all out as junk. I'm sure it's still available somewhere and it was fascinating they put a lot of thought into what they wanted to do. I don't know if it's true or not but I was told the whole purpose of the Germans who were building rockets for Hitler was really to launch rockets to the Moon. I often wonder what would have happened had the United States in the Soviet Union collaborated since we split up the German scientists involved
