Perhaps it wasn't just the pitots that iced up, but so did the statics but there just happened to be no acars which pointed to it
Well, yes there was, but everyone has suspected the pitots were the problem. Whether the static ports were also involved, we will never know. Ice reverts to water and all traces that could lead to your static port theory have gone forever - subject to the CVR revealing that the pilots had no meaningful info from the standby altimeter.
