Working with mocap sucks. The easiest way to do it would be to animate in Maya and export the animation as an fbx. If you animate on a rig that is compatible with mecanim, then any character that is compatible with mecanim will work with the same animation.
Animation is for the legacy animation system, animator is for mecanim. You can run both on the same object, but you’d have to be careful and make sure they sync up
