Well the 30% itachi clones was said to be unable to use MS.
The edo tenseis have unlimited chakra, meaning not restricted in number or quantity...It doesn't allow for an unlimited amount of chakra to be used at once, but they do not run out of chakra and they regenerate it almost instantly we know Itachi can make clones, and we know the use of abilities while being an edo was not draining his chakra...
Even if his max his at one moment 4 clones, then He can make those 4 clones with susanno, Then 4 more, and repeat...
We have no idea what Itachi's maximum container of chakra is or isn't... His stamina is low, but as an uchiha, he had a decent amount of chakra from being born with unnatural mental energy
Say Itachi makes 2 clones (plus his real body) that would make the clones have about 33.3% of Itachi's max chakra, i'd say this eliminates the thread of Amaterasu/tsukuyomi.
He might be able to use susanoo with them 3 clones but to what level them susanoo would reach is questionable.
