Looping levels

Would it be possible to use Level streaming + world composition to create levels in which at some point it would loop back around similar to how the levels were back in Star Wars Galaxies or Kerbal as a more recent example? Also would it be possible to use the system to go from space to the surface of the planet even if it is done in layers?

Did you get anywhere with this? I would like to do the same thing by the sound of it, so if you got any answers, I’d be grateful to know.
