I'd like to note again, If Nagato has access to Gedo Mazo in this thread then Madara has no chance.
I'm curious here. Why do you say this?
Put it simply, If the soul dragon touches madara it's pretty much GG.
The Soul DragonYou must be registered for see links. Meaning it only phases through Human bodies to take their souls. So its not going to phase through Susanoo so Madara is safe.
Already aware of that and I agree with you regarding that aspect, was merely saying it just soul happens to touch him by chance it's over. U_U
