But they had to be dead for kabuto to do the edo tensei on them... didnt understand what u said:S
you can not use edo tensei and revive someone whose body you don't have.
that is exactly why kabuto could not revive the first, second, third or the forth hokages. all 4 of them are in the belly of the death god.
The same goes for Jiraya. Tobi could not find his body as he drowned in the ocean
