I had a thought. Is it possible that there was once a fifth large moon in the Jovian system - maybe not another Galilean, but at least a Rhea or Enceladus? And perhaps it was ripped apart by a collison with a kuiperoid in Jovian orbit. The pieces of it, mixed with the fragments of the impactor, may have never been able to reassemble given the tidal environment, but instead formed the rings and the little group of inner moons. If the kuiperoid was much larger than the satellite it hit - but coming at a high enough relative speed to be shattered anyway, that would explain the lack of rocky materials. Any thoughts on this?
