Revision rates at the MR stage are very low but they do happen, I can't advise what is the best course of action for your client, submitting or not submitting evidence to the MR may not significantly affect the time for a Decision to be made.
Be aware that any deterioration on your clients conditions since the original Decision cannot be considered by either the DWP or an appeal panel.
