I'm willing to bet Oda is going to do something like that towards the end. Kid somewhat parallels shiki in that he is Luffy's rival as Shiki was Roger's. I think Kid's awakening could in theory work very similar to shiki's power, with kid being able to make objects levitate by magnetizing them.
I think that similar to Shiki, Kid is going to get a giant armada by the EoS by conquering the other supernova in the new world(obviously, bar Law and Luffy). This will allow Kid to replace Teach/shanks as yonko.
I don't think Law will ever get a big crew. I think he's more of a lone wolf, kinda like Mihawk. He's not a conqueror like Kid or Luffy.
