I'm sure the 96 kHz converters have not been designed for this kind of application. Only choise is to record with the normal speed. It could be more realistic to buy multiple cassette players. That would reduce the digitization time easily. You would not need quality players if you have only speech on the tapes. The neat thing is that multiple players would reduce your idle time as you would need to change the cassettes all the time. If there would be simple robots available, one could leave the cassette changing to the robot.
