Could changes in any contributing factors have reversed the decline of the empire? Why or why not?

Historians generally agree that the Roman Empire began its decline at the end of the reign of the last of the Five Good Emperors, Marcus Aurelius (A.D. 161–180). The rulers that followed in the next century had little or no idea of how to deal with the problems facing the empire. Most, like Aurelius’ son Commodus, were brutal and incompetent. They left the empire greatly weakened.

Well, to answer how you could have reversed the decline of the Roman Empire, first you have to decide why the Roman Empire declined. Nobody can agree on that. Plus, there were two Roman Empires after the formation of the Eastern Roman Empire, and the Eastern Roman Empire is a completely different situation because it lasted for another thousand years after the Western Empire ended.
