With that addition, I will now move on to the big stuff.
Doton: Domu was said to be as hard as a Diamond in which shares characteristics to that of Monkey King: Enma.
Monkey King Enma's transformation technique, which is characterized by the hardness of diamond.
With that being noted Doton: Domu itself within the Databooks was hinted to have diamond like properties when Kakuzu activated this defense:

Adamant and similar words are used to refer to any especially hard substance, whether composed of diamond, some other gemstone, or some type of metal. Both adamant and diamond derive from the Greek word αδαμαστος (adamastos), meaning "untameable". Adamantite and adamantium (a metallic name derived from the Neo-Latin ending -ium) are also common variants.
Adamantine has, throughout ancient history, referred to anything that was made of a very hard material. Virgil describes Tartarus as having a screeching gate protected by columns of solid adamantine (Aeneid book VI). Later, by the Middle Ages, the term came to refer to diamond, as it was the hardest material then known, and remains the hardest non-synthetic material known.
Diamond, and Adamantine are similar in which the same feats can be given to Doton: Domu that were given to Monkey King Enma's transformation technique: Henge: Kongōnyoi
So let's take the feats from Enma's adamantine structure, and give them to Kakuzu's Doton: Domu:

It is also arguable to say that Doton: Domu due to it being the hardest materia within the NV, along with having one weakness (Raiton) it could possibly tank many other things. This statement in which Kakuzu himself had iterated stands true, excluding Raiton-based techniques however:
