[Opinions] As in Hades?

That's the first and only association that comes to mind, and it's a bad one. Haydey is just "heyday" but weirder. I really don't think it's usable unless you're in an area where people are clueless regarding Greek mythology (or just clueless in general). I have never met anyone with the name. It does sound made up, and that's uncommon with Greek names. You could do much better.
