Minato would beat Kakashi with ease. As shown in the series, Kakashi has so little chakra it takes 'half his chakra to make one shadow clone/lightning clone.' And just for comparison, Shizune is able to use the multi shadow clone jutsu and almost match Naruto's number in shadow clones.

As for Kamui, Kamui would be pretty much useless against Minato while he's using FTG, which is main battle tactic.

So unless Kakashi was able to determine ahead of time which Kunai Minato would pop up at and perfectly time a critical blow with Kamui, he wouldn't have a chance.
