Well anyone with good chakra control,large pool of chakra can become any sage out of toad or snake or shikko'whatever forest[slug] sage. People saying no are delusional. Kabuto is an example. Minato says hi,and jiraya I guess is just forgotten here.
And we all know all 4 descendant clans of sage have large chakra pool- senju,uzumaki,hyuga[there each and every attack use massive chakra aka rotation] and uchiha[susano'o is nothing but a physical manifestation of their spiritual chakra and boy it's comparable to tailed beast].
