If Minato couldn’t be bothered to use SM because it affected his fast-paced fighting style than i’m pretty sure he wouldn’t bother himself to expand his arsenal. Also, his “fast-paced” fighting style already seemed to have peaked, so IMO he wouldn’t have become much more powerful have him not die. Also it seemed that he concluded himself unable to add chakra nature to the rasengan, so that flopped as well for him.
