Six paths Sage Mode is a combination of NY and six paths chakra. Six paths Sage Mode is a Six paths Senjutsu, the same way Normal Sage Mode is a Senjutsu. The reason why Madara or Obito did not use Six Path Sage Mode it's because they didn't mastery over SM. So they only used other six paths senjutsu attacks like Sage Art: Yin Release Lightning Dispatch. If Somebody like Hashirama who had prior mastery over SM would aquire six paths chakra, he would also be able to use six paths sage mode.
