It also depends and how strong is your chakra. In the end, the rasengan is just chakra shaped. For instance, even if Minato would master change in chakra nature rasengan, it would probably still be weaker than Naruto’s base rasengan.

Probably Minato has stronger chakra than Konohamaru, but Konohamaru’s wind rasengan seems to be no joke.
