This has been done, and doesn't work especially well. See, for example, GANs, which are difficult to train and vulnerable to mode collapse. Not saying that it's impossible, but reinforcement learning of the form shown by DeepSeek was particularly well-established and robust. It's sort of ironic, actually...IIRC, OpenAI started in the world of this kind of reinforcement learning.
