if he tag a clone it's just that clone then,not all of them + original (doesnt that use chakra also) so trying to tag every clone is going to be a hard task IMO
Also minato wont even know how many clones naruto makes in the first place so naruto can easily hide himself somewhere (the ground,turn himself into a rock like when he fought pain,etc)
Naruto make rs out of his A** his clones can make 3 rs for each clone
Naruto wont be using any of his chakra while in km because now kyuubi is willingly (is this a word lol) giving naruto chakra (shown in manga,the clone was out of chakra completely couldnt even go sm again but then the kyuubi gives him enough chakra to make swarm of clones and about 6 giant rasengans)
