Minato lost one of his hands, so he'll have a hard time forming the necessary seals to use the Reaper Death Seal on Madara.

But as we've seen during Naruto's training with Bee on the giant turtle, opening the seal only requires one hand, so transfering the other half of the Kyubi into Naruto (or more likely setting it free and allowing him to enter Naruto of his own will) might be possible.
