That wouldn't solve the fundamental issue of supply and demand during a mining craze. Mining crazes appear quickly and dissappear quickly leaving little opportunity for the much slower silicon pipeline to catch up. The demand for cryptocurrency ASICs in the last mining boom was much higher than the production. Thus even if they could meet demand that would just result in less allocation to gaming hardware. The reason it has been successful for bitcoin is becuase sha256 utilises only half of the gpu whereas memory hard algorithms like ethash utilise almost all of it. Designing a specialised, power efficient ASIC only matters when the return isn't ludicrous. During mining bubbles it makes a lot more sense for miners to purchase general hardware to use during the craze and sell afterwards. Until these bubbles aren't as crazy that's not going to dissappear.
