It also assumes he can take hundreds of atmospheres of pressure (for depths >1Km). I don't see the Raikage going this deep.

I already mentioned the time constraint. Sure, if given enough time someone will invent a way to dive to infinite depths. If given enough time, any jutsu can be invented for any purpose. Even in the real world capability is often simply limited by time: given enough time, a human can dive 11km deep.

But that's not the point. Within the time he had, he didn't have the capacity to get to the body, or he would have. Just as i commented earlier.
