Wasn't something similar like this done with the Xbox (or Xbox 2 or whatever its called) to mine Litecoin back in 2013.2014? If I recall the GPU inside the Xbox was the Tahiti chip Radeon 7950. That GPU was more or less the 7970/280X with a slightly lower core clock however it was the most efficient GPU to mine LTC at the time. And late 2013 GPUS were sold out everywhere so people decided to try and mine with the Xbox instead.

I have a feeling that if this is possible there will be a shortage of Xbox's everywhere due to GPU mining. So far all GPUs are sold out. Now people are buying gaming desktops and gaming laptops with GPUs inside to mine and if its possible to mine on a console then miners will start buying Xbox's and Playstations next. Crazy times...
