"can the fault detection system work fast enough. "

Well give it was mostly hard wired but IIRC there was a very slot processor in the loop (sub 1 MHz) I'd guess a 200MHz ARM would be substantially faster, or a discrete ECL SSI logic chip design at 1GHz (it'll guzzle electricity during the minutes of launch with the escape system is usable, then shut down).
