Can you pleat crepe-back satin?

Yes you can pleat crepe back satin. Pleating any fabric is something for a seasoned sewer or one that has a pleating machine. Have you check the price of a seamstress pleating fabric. I would think they would charge a lot to do it. To hand make pleats all the way down a dress and iron them in is very very time consuming. This process is usually done by an industrial machine.
