Hoppe swing door look

I am replacing all of our interior door hardware with oil rubbed bronze finish. I have three patio swing doors, and I am not sure if I can just replace the interior faceplate, handle and knob, or will need all new locks sets. The house is 20 years old, and these are the originals. I have tried to determine the manufacturer of the doors, but no luck. The top and bottom screws are 7 7/8" center to center, and the handle and key/knob holes are 3 5/8" center to center

We are repainting the doors, so the faceplates can be different than the original.
