in reality if minato/kakashi, jiraiya wanted to add an element to there rasengan they could in fact easily do it. all they would have to is form a shadow clone then in the original body form a rasengan. then if say kakashi wants to add lightning to it. he could add it with the shadow clone if jiraiya wanted to add fire to it his shadow clone could just blow fire into the rasengan. its the same way that Naruto and Yamato mixed wind and water release or how naruto and sasuke mixed naruto's rasenshuriken with amaterasu. it's just that naruto was the first to suceed. even in the boruto movie Boruto didn't suceed in creating an elemental Rasengan he simply created a rasengan that dissipated and turned into a small wind blast
