Is it possible to extract a position and rotation of one of the Rive internal hierarchy objects, translate it into control-space and use it as a binding for a RenderTransform?

I want the movement of a Rive widget animated within Rive but the overlay text/image to follow that animation. I realize images in Rive are not supported by Noesis, I mean overlaying a RiveControl and an Image (or text) element to achieve a result that's similar to having the image be part of the RiveControl.

That won't be possible, but we are working on supporting Rive files that include images (and next text) so you can have them directly inside the Rive animation.
