Even if they were cheaper miners wouldn't like them: one thing which substantially reduces miners' operating costs is the resale value of the GPUs they are using. They can buy a GPU, mine on it for a year or two, and then sell it for ~50% of its original value (or even higher in today's markets). The mining cards with zero resale value (which will much more quickly become landfill) would need to be substantially cheaper to make this worthwhile.
