Ok **** all the rest i'm focusing on you >.>
First off i highly doubt their undetectable are you trying to say Zetsu beats Kakuzu 0.0
No matter as this is dealt with Easily, they definitely become noticeable when absorbing Kakuzu's chakra, all he need do is activate Domu, then continue to fire either his wind style

or fire style

at himself which he obv is capable of doing, this would either melt the spores on him while he is safe inside domu, or blow them off him while he is safe inside Domu take your pick
As for your other points, come on People (myself) included overstate Oro's durability prowess, Yes his body replacement is a pain, but we all know it takes a great deal of chakra, not to mention theirs a simple way this is countered really, After a few times or possible even one of Kakuzu striking him with Jutsu, as he really has no means to avoid any of them, or even block them for that matter as he has no summons and no Rashenmon he will clearly figure this out, merely pull out Oro's brain U_U This is not tsunade we are dealing with his regeneration is not automatically kicked in, he has to activate the Body replacement jutsu, which he is not doing without a brain to initiate the process,
That pathetic Hydra that has no feats except being sliced apart? LOL at you saying it crushes something that can fly around the hydra and continuously blast it with jutsu they would also obv not start immediatly under the hydra's heads sp not seeing how it crushes them before they get all that high, as we saw its not all that durable if anything the Lightning stlyle can pierce it as many times as it needs too, Extended Kusanagi? Lol perfectly aimed at the masks, i doubt it even so its not touching them as if it gets too far extracted from his mouth he loses control over the sword

Nothing suggests Oro's Hydra mode can tank anythign really
