It would be dead simply to imply such an acceleration alarm, be it based on FMGES performance data base or with the RIPS or ROPS or other systems.
One of the problems associated with putting such an alerting system in place is that they would still require a human input into the system so that the nominal acceleration rate could be computed. It would still be possible to mis-program the FMGC to the point where the alert wouldn't be effective.
The best SOP I've seen to prevent such gross errors is an independent check by two or more crew members, where both do the calculation independently. In addition to comparing their computed results, the crew also must compare the calculated TOW with the one on the operational flight plan. Discrepancies must be investigated and resolved prior to takeoff.
