The funny thing is this thing actually happened. There was a chip called the Lucid Hydra 200 that allowed the user to combine a Nvidia card and an AMD card in multi-GPU configuration. They did it by intercepting the Direct3D calls and selectively delegating them to each GPU.
It goes without saying that it didn't work anywhere near satisfactory levels, but kudos on them for trying.
