Considering he summoned Gamabunta and teleported Bijudama and Kurama himself, his chakra levels are massive. Naruto needed Kurama's chakra just to do the same. Kakashi needed Kurama's chakra to Kamui Biju.

So no, that doesn't work. If you compare Minato's complaint to Naruto use of sage mode versus Nagato, you'd see that Minato is simply still a novice sage. He's as far as Naruto was when he just achieved Perfect Sage Mode.
