You present good ideas.
If _you know where the axle connects on mata/nuva head you'd replace that so it'd be able to bend and rotate while otherwise working like an axle. I can link a video later. As for colors of the masks, that should just be a paint job once it gets to having them available. Painting them would probably be the furthest I'd go as modifying the parts would be hell. I'll look at modded versions when I get a 3D printer (as if I'd get)
