I don't think they make one. I've looked through all the suppliers as I have Babylock Serger and Coverstitch, and Pfaff sewing machines. If I look for a part for one, I check for all the others. The needle plate is hinged. You might try as suggested to see if twin needles will pick up the bobbin thread, then buy another single stitch plate and widen the hole with a Dremel. If you have a serger with a coverstitch built in, I'd use that. I can see the point of wanting to use the 1500 for more - I prefer it for zippers rather than the Pfaff 2170. Sometimes electronic machines controlling settings can be a pain. I prefer to control presser foot pressure myself rather than the machine. My Imagine serger is mechanical, so is the coverstitch, and I can adjust there. BTW - a coverstitch doesn't have a knife, it will do pintucks, use a binder, hemmer, and more.
