You are not entering France or Schengen, so no contrôle passeports or luggages. You arrive at 2E and will simply go to the departure hall/gate (likely K or L in your case), staying in the same terminal. You may pass thru contrôle sűreté when arriving from the US; you will pass through it when arriving from the Maroc. So I would say anything >60mn is fine.
