Yes, the New Olympus RS-31 Foot Pedal will work and allow you to control the audio playback with the Olympus AS-5000 (DSS Player Pro Transcription Module), however; you must have the latest patch (Release 5.0.13) and you will not be able to customize the foot pedal settings as the RS31 is not an option on the customization drop-down menu within the Device Settings.
