Me thinks you misunderstood Shadow's post.
No comment on the 3x durability, susanoo are retardedly sturdy as is so that doesn't really change anything, but immunity to any and all non-naruto things without question is basically godmod. It doesn't really matter where you say its power comes from, you're still claiming you will be stronger and invulnerable to them no matter what, in short a god. Some might consider this insulting since not all such things are acad level bullshit but well written instead, if not a bit hypocritical too, because technically this thing of yours is not canon at all either. By interacting with them you're basically acknowledging their stuff exists, so what I fail to see is if you dislike non-naruto things so much then why don't you just steer clear of them instead of resorting to stuff like this.
As for the susanoo themselves, in theory a sufficiently powerful clone could make a susanoo around itself as Madara's clones did, even put senjutsu in it if they took the time to gather it and managed to synchronize the two powers. Its your execution of it however where the problems come in.
First off susanoo never act independently from the user, it always requires either the main or a clone body inside to keep it together and control it, because its just a mass of chakra without a will of its own and without the controller body inside it just disperses, simple as that. You claim to get around this by using Kabuto's inorganic reincarnation to turn the susanoo themselves alive, going past the original because senjutsu hax? Can't agree with you there, because for one you seem to forget Kabuto himself was already in broken level of sage mode himself, in fact its debatable he'd be able to use it all without it, and even then he never actually brought the environment alive, he just animated it according to his own will as if it was.
I could maybe see that if you had some way to keep a susanoo together away from your body, you could technically remote control it or something through Kabuto's trick, but considering its size and all it'd still be a considerable chakra drain, especially with as absurd a number as 25 or what was it. I dunno about others but I don't see how'd any normal human ever have the chakra for that, even I myself am not that crazy.
Regardless, this wouldn't really leave much choice besides to just copy Madara and make actual clones to control and stroll around with those susanoo. While a kage- or mokuton bunshin could in theory persist around a while like this, they by no means would last infinitely. Naruto never could keep any significant number around for long before they'd forcibly disperse and he'd collapse from exhaustion, not to mention kage bunshin also divides your chakra between all of them so the main you would never be anywhere near your full power either, if keeping that many around had the power for susanoo anyway. Mokuton bunshins drain in turn was never truly shown as Yamato never made more than one, and Hashirama was an edo tensei. Hashirama did however pretty clearly state the freshly juubi-hosting Obito would still be stronger even if he dispersed all his wood clones, so at least to me that's pretty clear proof mokuton bunshin also divide your chakra away between yourself and the clones.
So, long story short, I don't particularly care of ame, nor if you pull the 'nobody ever complained before' card or someone else the 'stomping on creativity' one on me. However I would advise you to look in the mirror first next time, before you get on someone elses case while trying to justify your rather absurd jutsu.
