This is actually a good idea. But wouldn't it drain the mobile out? Will the manufacturers be able to create a mobile that could stand the mining system? A computer/rig which is heavy duty compared to a mobile heats up and consumes a lot of electricity. Now what do think would happen to a mobile? Now let's say that the manufacturers were able to create such mobile which is specifically designed for mining, I bet it will be priced quite expensively! Just a thought...
