Maybe, and yes

Not sure I agree - they original warnings appear to have been ignored or discounted. If anything, intermittency might lead to more chance of recognition. It appears they thought they were overspeed and distrusted most or all instruments and did not believe the stall warning. I think there is a good chance they would have disbelieved a continuous warning all the way down too.
- the complexity of the FBW system
Why ? As far as I can see from the info we have now, if they had done the same in conventional controlled a/c the result would ahve been the same.
- lack of AoA information
Would they have looked at it ? Would they have trusted it (remembering it would have gone invalid at some points) ?
- poor handling proficiency
System failed the pilots by a lack of training - or at least BEA seem to think so.
