Well obviously nothing is impossible, but this sorta work is about as close to literally rocket surgery as you can get. Software: difficult, hardware: difficult, thousands of dollars of specialist equipment, and the steady hands of a surgeon. There's a difference between possible and "possible".

also there's a difference between devising a technique for a model, and doing a repair on this specific device. To get to a working technique you probably need to brick a lot of machines.
