His body will already be activated in Sage Mode despite his current situation of not being able to control chakra correctly. Maybe he could use brute strength and will himself out of his situation using his Sage strength. However, I'm not sure if that's possible because Naruto's chakra system may be too screwed to except natural energy due to the chakra rod. So I'm not sure if the first method works.
I do agree however, Naruto can't do anything unless he breaks free from the chakra rod. So he'll have to use the Kyuubi's chakra if he can't do anything else. The Kyuubi has shown to be able to disrupt Fukaksu, so perhaps it can reject Pain's chakra.
pain has a hold on him right now, even if the clone gets back and poofs it wouldn't work he would get the sage chakra he would then lose it cause he cannot maintain it. the only way to maintain is to mold it the right way which u can't do if the rod is in you.
kyuubi will def play a role and yes it will easily push pain back if it was able to push back fukasaku..
