He used the technique immediately after he was released from the Edo Tensei, there was no charge time.
I agree that Oro might still have some CS's hidden away. But Kakuzu? He isn't attacking hearts, he's going straight for the soul. Same with Hidan, he would just cut his own head off while in his body.
Susanoo is tangible, he goes through all things tangible as he is intangible, he is a spirit, a ghost.
I guess the clones could work, but the only known weakness has been stated as a specific barrier jutsu that doesn't allow the soul to escape.

Here he tells them to "hurry up before its too late.." Implying he has to wait till he can use it! SO there seems to be a waiting period before the tech can be used.
1. There is no reason to not use the tech asap just like every other edo tensei being controlled.
2. He is not in control, so its not like he is "waiting to use it" on his own free will. Remember kabuto has them all in battle mode and use your jutsu mode.
3. It would make no sense for Kabuto to "wait" to use the jutsu, even after dan telling them to hurry up. So this means the justu has a charge time or waiting period to use.

Now moving foward. As you knwo Dan has been in that barrier for awhile now. More then enough time for the jutsu to be "charged up" and ready for use.
Also when the jutsu is in use, everyone can see him.lol

So its not like they would just stand still and let a "ghost" come at them! lol
Another thing..
If he kills your soul/spirit/essence wouldnt your soul be able to make contact with him aswell? Just like him and tsunade making contact in the spirit world it would seem?
