From my understanding of orbital mechanics and of how solar system form, it is extremely unlikely that a globular solar system would form. As a gas cloud contract to form a start the angular momentum of the mass will bring the mater in a relatively uniform 2d plane around the star. To have a more chaotic system would most likely take the intervention of a large mass coming into the system and disturbing it or the capture of a non local object. For example, the moon Triton around Neptune turns t…
