But at the same time all of OP's points still stand. The intended specimen still provides the framework for reanimation, and Kabuto tampering with Madara further suggests that this base potential (like how many chakra [units] it has) is still as important as ever. Just how far we can play around with the rules is up for anyone to guess.
Well this was obvious? That is why Madara had crep Susano's when he used 25 clones. His chakra was split in to many places...
For starters, the "body not being strong enough to use the technique" is false. Nagato, who had arguably the weakest body outside of Madara, had LOADS of chakra. And that had nothing to do with his Rinnegan, but was due to him have Uzumaki blood. Fact of the matter is, some people have loads of chakra, others don't. Skill is often what separates people from using techniques, not the physical capacity to do so.
Konohamaru can't use Sussano because he isn't an Uchiha and because he isn't skilled enough to do so. Konohamaru is actually a terrible example given the fact he can use high level chakra jutsu in the form of Shadow clones and rasengans and still has energy left over.
Now, saying the body has limits is a possibility, but Edo Tensei seems to destroy these limits in the sense that these bodies don't tire. If you don't tire, you can't run out of physical energy as an Edo. Undying spirit w/ unlimited physical energy gives you the capability to use any technique if you have the required skill and special abilities (kekkai genkai).
As for the bolded part, Muu couldn't use Jinton because his spirit split and thus something happened to his affinities, as they were split up between the two bodies. What happened is the exact opposite of you what you are stating if I am correct.
Bit off topic, but don't want to start another thread on this question: Can Madara be sealed? If he resisted EDO release, can he be sealed with sealing jutsu for example from Sai, or can he resist that too?
another weakness of edo tensei is that a person won't be able to do any new techniques or techniques that causes their natural abilities to grow. i'm thinking that's partly why madara didn't want to be a zombie; zero capacity for growth.
Where & how did kabuto get marada DNA?
from what I understand about Edo Tensei Chakra. It wasn't infinite but rather fast chakra restoration. It was like saying having an Edo Tensei Body makes you immortal but in reality it restores your body from being destroyed making the "immortal" word true. Feels like their getting chakra from another dimension or world since they came from there
Well , look like everyone have infinite chakra in mighty alliance army , so Madara isn't problem ....
after all , it said Madara had extremely strong chakra in Uchiha and now he had Hashirama's cells and Rinnegan ...
that corpse ( Nagato ) has enough chakra to teach a lesson to konoha !!!
Kishi already break his own rules so don't except any logical expiation about this ....
The "infinite chakra" seems to come from the extreme regenerative ability the zombies possess. ET Zombies don't suffer fatigue and run out of chakra because of the jutsu's regenerative capability.
Therefore, in theory, you cannot go over your potentials with Edo Tensei. Say, if Kakashi died and then, he was to be revived with Edo Tensei, he would be able to spam Kamui, since it was something he was capable of, albeit with a usage limit. Edo Tensei impinges on that limit.
So, technically speaking, if Nagato wasn't stopped, he would be able to use Rinnegan's abilities to such an extent that he could have destroyed a fair share of the allied forces alone. This may sound absurd, but if you consider the fact that many of those Shinobi had trouble dealing with Zetsu clones, that isn't the case for me.
Susano'o isn't a good technique to look for. It's been passed on by Kekkei Genkai. Hence, it's not very relevant with the debate here. The best example would be the Eight Gates. Gai can open all of them, while others cannot. But it certailny has nothing to do with genetic heritage or whatsoever. Lee can also open five gates and it's beyond what more refined, skilled shinobi can do. It's just training. But those people revived with Edo Tensei cannot do this, either. Because they do not only regain their capabilities, but also the memories of training. It's a bit like Kakashi's technique copying trick.
In other words, you cannot regain the memory of yourself doing something you didn't in your real life.
