Should I need Epic Skeleton for root motion?

I searched alot for root motion but i didn’t get a regular answer it.
I want to use Mixamo for my custom character. I dont want to use Mannequin skeleton or animations. And for some animations I need to use Root Motioned Montages. Can i make it? And if you know how please tell me.
The model is modeled in Maya and rigged in 3DMax Cat.
