Mixamo auto control rig - face rig

Hello everyone,

I am in the middle of my animation made in Autodesk Maya and I need few more characters with face rig. Because the fuse was shut down, I can not rig the face rig.

Would it be possible to copy face rig from older characters (made before Fuse was shut down) into new characters and rig it with Mixamo auto control rig?

Or is there any other way how to do the face rig? Please help me, I am desperate.
