I think it would not be not too difficult to implement a check in the flight data processing system that verifies the actual aircraft type based on the ICAO 24 bit address in the Mode S replies / ADS-B squiters. The data is there already, all that is needed is a database that links the 24 bit address to the aircraft type and there you go. Maintaining that database up to date is of course critical for such a system to work.
