VicMel,
I'm afraid you're barking up the wrong tree...
Events with two out of three pitots icing up synchronously, with the A/P "believing" the wrong data, and similar strings of fault messages, have already happened.
They didn't lead to a crash, because the pilots understood the problem in time, and used "pitch and power" to "fly out of it"... which is why we have the full sequence of fault messages from the FDR, rather than a fragmentary sequence of ACARS messages.
The very recent Airbus memo about not re-engaging the A/P too soon after a "loss of speed data" event also clearly points to their thoughts about the subject.... bearing in mind that they may not know a lot more about what actually happened to AF447, but that they know a lot more than we do about how the systems and aircraft would behave in similar circumstances.
