Kabuto could've performed Edo Tensei on several people, then had those people perform Edo Tensei again to summon sets of other Edos. I think the problem with this is power: Kabuto was able to bind all these people to his will and summon them at pretty much full strength. However a nested ET would mean that with each nesting the power of the next ET drops and the binding gets weaker.

So it would quickly become a very weak jutsu. It also raises questions regarding how properly Kabuto could control these ET, and opens up significant weaknesses.
