In fact the A320 system does something very similar when it compares the gross weight calculated from air data and inertial data to the gross weight calculated in the FMS from loadsheet and fuel used. In case of a discrepancy, a CHECK GW message is generated. (See Perpignan Final report). I don't know if that function is available in the A330. Using that same logic in reverse the airspeed could be calculated from the FMS weight. The BUSS presumably does something similar.
