Lord of Kaos wins, no doubt there, Kaziname already died after LoK first attack of Water Explosion, Weight of the World and Earth Annihilation. You overestimate Assimilate all Creation Technique way way way way too much. Just because you had the idea of using diamond rings you think you found one of the most ultimate defences as diamond is so hard and that you can reassemble after every attack.
Wrong. It's still only a C-rank jutsu, so that defence, whether it's diamond or anything else, is C-rank. For some reason you completely ignore the basics of RP battling. If diamond armour would be that indestructable, the diamond element would be seriously OP. Do you think a C-rank diamond jutsu would survive an S-rank water and two S-ranked earth jutsu's? No, that would be directly unacceptable but still for some reason you think it doesn't apply to you. Why? Because you can reassemble? If you could do that after every attack then the guy who used that jutsu in the anime wouldn't have lost from Kakashi.
Tell me why didn't he reassemble when Kakashi hit him with the Chidori? Because earth is weak against lightning? Lightning destroys earth, so in fact it would do the exact same thing as you turning to sand. Still it beat him. Highely likely because lightning chakra beats earth chakra which he was pretty much using, the same goes for when used another elemental jutsu. In the end if the jutsu is so strong the chakra would just crush that C-rank jutsu, no matter which material it is and whether you reassemble or not. Saying that he survived an explosion is not an argument either. That was an exploding tag and the result were chunks the size of arms and hands, which makes it pretty realistic to still reassemble. After those S-rank jutsu's there's nothing left of you anymore.
That you're diamond doesn't mean anything either as it's not even real diamond, only a copy produced by your chakra. That's something Kakashi even stated at the end of the battle that he's still only copying jutsu's. It doesn't matter if your diamond or earth, it's not really a big deal, those S-ranks killed you. Then we get to another point, even though it can never be proven completley, it's highely likely you can't even use water jutsu's when using that jutsu for the simple fact you're using your chakra permanently for as long as that jutsu is active. In the anime that guy only used earth based jutsu's or ninjutsu that can be used in conjunction with his body of rocks, using elemental chakra is something completely different or do you think that guy would have been able to preform a Chidori himself? Using common logic it would be highely unlikely for using any kind of elements other than the one directly applied.
That jutsu isn't much different from Suigetsu's body, still his body isn't that much rated apparantly as your jutsu, while it's nearly exactly the same, can survive nearly everything while Suigetsu's body is certainly not deemd the same. It can survive small explosions and hits, however large jutsu's not. You got hit by 3 S-rank jutsu's, so you're completely dead. Even elemental weaknesses don't apply anymore as the difference in power is so big.
In the end that ninjutsu, diamond or not, will only be able to survive things like exploding tags, kicks, hits and low lvl offensive jutsu's. Every A-rank offensive jutsu will beat it, most of the B-rank jutsu's will beat it and even several C-ranks will beat it. If I would use that jutsu in the same way as you, I could make myself nearly invincible.
Summary: Lord of Kaos won, it's not relevant what happend after that. Kaziname died.
