Having Hashirama's cells doesn't mean having Ashura's power. Ashura moved on after Hashirama dies, while Hashirama's cells were taken from his body after he died. If they were taken from his body while he was alive - like Madara did - it would probably make Yamato (and the others) some kind of successor, yes.
