Well, seeing how Naruto and Sasuke "just" had to touch Kaguya at the same time to activate the Six Paths Chibaku Tensei, it feels like it was pointless to take out Madara, since Naruto and Sasuke didn't realy have many difficulties in attacking the older Uchiha (albeit with the latter having only one Rinnegan at the time).
