So, it sounds like you want take a 2D photo of a pose, and convert it to a pose that can be dropped onto a Poser figure? 

Theoretically it would be possible to have an AI do: 2D image -> OpenPose -> convert 2D points to 3D points -> generate a retargetted .BVH file suitable for dropping onto a standard Poser V4/M4 figure.

The first part of that is relatively trivial and already here, handled by ComfyUI and Openpose. And it sounds like that's also now integrated into even the basic version of Clip Studio. Then the Openpose converter part would probably have to be 'vibe coded' by something like Grok, after being fed documentation and some examples of the Poser-friendly Carnegie-Mellon .BVH files.
