Zoroaster as Nietzche's Zarathustra, in Ancient Greece

I had a crazy idea for an alternate time line in which the Ancient Persian philosopher Zoroaster; instead of being the founder of the religon of Zoroastrianism, was instead the prophet in Friedrich Nietzsche seminal work Thus Spoke Zarathustra. In addition, in this time line Zoroaster is not a Persian, but a Greek (in keeping with Nietzsche love of Ancient Greece). In this time line Zoroastrianism is not the religion it is in our time line, but a philosophy or school of philosophy in ancient Greece, probably starting at the time of Homer or shortly after. Is this even remotely plausible? Am I staying up way to late at night?
 
It is vaguely possible. During the period where philosophy flourished in Ancient Greece, India underwent a similar movement- Buddhism was born from it. However, at the same time, there was a movement that was oddly similar to Nietzsche's thought, IIRC. A nihilistic materialism, basically. You could posit that the ideas of that movement arise instead in ancient Greece.

As for it being Zoroaster, drop that. Welcome to the forum.
 
Zarathustra is just a literary cipher for Nietzsche to vaguely expound some of his early mature thought, really. I wouldn't put too much credence on trying to recreate Zarathustra as a real person, much less a real person with their own philosophical model. I doubt even Nietzsche had his entire philosophical worldview worked out be the time he wrote Zarathustra. His works after Zarathustra were a lot more systematic in laying out his thoughts which he'd developed in Zarathustra.

The idea of Nietzsche as an ancient philosopher is a pretty neat one though, although I doubt he'd fit in with any of OTLs schools.
