Tecniclay if the chacra is ur spiritual energy combiened with the fisical energia he can tecnicaly copy any quirk if is just the moviment of the chacra
Technically, the fact that Yuta was the one that beat the Nomu, and All Might did not have to exhaust more of his remaining power by fighting the Nomu. Should mean that All Might right now, is stronger than his canon counterpart, so he should be stronger in his fight against AFO in Kamino.
i wish you would have at least shown the interaction between Toru and Yuta while he was in the hospital. Character interactions are just as important to the story as the fight scenes.
Many thanks to the author for saying about such a thing as the work of a sharingan in a world without a chakra, although it has not yet been mentioned that for his very work it is necessary to feed the chakra through the chakrocannels into the eyes.
It would be very difficult for Yuta to find a quirk that he could copy. Since the Sharingan will not copy quirk resistance. That is, Shigaraki's Disintegration quirk will decompose him, Todoroki's Fire and Ice will burn him or freeze him. Quirks that change the body he won't be able to copy either.
