I don't think DE Luke would be able to defeat Windu.
Luke gained most of his power after establishing his Academy on Yavin 4 and before that he was quite untrained. Jorus / Joruus who was clearly a PT Jedi not on Mace Windu's level outclassed him one year before DE and Sidious - who was beaten by Mace in a lightsaber duel - managed to disarm Luke in their first lightsaber fight in DE.
Now add that Mace has far more force control compared to Luke and was a lightsaber prodigy on his own. Add some years of actual (lightsaber) battle experience on Mace's side and his unique Shatterpoint ability and Luke would get owned pretty much.
On the side topic of Greek Gods vs Norse Gods:
The Norse Gods would curbstomp the Greek ones. They are far more martial (especially the likes of Thor, Odin and Tyr) and more powerful to an extend that they slaughtered entire armies of giants singlehandly (Thor) and even killed other Gods (Odin). I mean really...it's known that some leaders in Nordic had their ancestors kill them putting spears through them because this was the only way to reach Walhalla. Northern mythology is filled with so much violence that it makes the Greek Gods look like innocent children. Or let me put it like this: Thor is the mythological version of Chuck Norris and Odin is his superior.
I doubt that, dude. Thor was able to lift Jörmungandr, a serpent so large it encircled Midgard, a good four feet off of the ground. That's not factoring in his hammer, which is disgustingly powerful. Thor could very likely put Zeus on his knees, and Zeus was easily the most powerful of the Greek Gods.

Norse gods were apparently giant sized, since they interbred with Jotuns all the time.
Not to mention that Odin, Ve and Vili killed Ymir / Aurgelmir who was apparently huge enough to provide blood to form the oceans, flesh to form earth and the entire sky was formed out of his scull. That is "giant". 😉
The great serpant... heavier than 9 planets... I think.
Thor lifted it.
And we've seen the Hulk lift 100,000,000,000 tons... Losing to the Hulk isn't something to be ashamed of.
And Marvel Norse Gods =/= mythological Norse Gods.
But keep in mind, Greek Gods were immortal... While Norse Gods were just extremely long-lived super humans.
