Just to make this very clear no Naruto cannot be saved the kinkaku's and Ginkaku's kurama chakra as it was extracted during Obito's turing into Juubito part, he said that he didn't need the entire amount of chakra of Kurama and Gyuki, all he needed was the bro's chakra and the tentacle of the 8 tails' so no Naruto can not be saved by the bros chakra
