Well this fight would be interesting since its obvious that Nagato beats both of them without much trouble. And if itachi and minato fight together, they will have good chance of winning.
Nagato full healthy and mobile, Pains powers, all elements, gedo mazo and sensor ability vs. itachi with his MS and Minato
nagato would have killed naruto and bee easily while being crippled and controlled, without the use of his sensor ability and gedo mazo.
and without the jinchuriki itachi and minato probably wont have the power to destroy chibaku tensei.
