Naruto and even Boruto applying a nature to their Rasengan is just a cheap way of trying to make them stand out. Yea I'm sure that Naruto of all people could do it, but Minato or even Kakashi couldn't. But then again he used clones to help him speed up his capabilities. But, perhaps the most ridiculous thing that happened was somehow Boruto applying chakra to the Rasengan without even knowing and even more without even have learned the Rasengan that long. This is plot at its best. No denying that. I have no doubt that Minato could have added a chakra nature at some point and even Kakashi at some point, but unlike Minato he died shortly after mastering it. Kakashi just gave up on adding a nature to it due to creating the Chidori aka the Lightning Cutter.
