The PRF files have the MDL name and "editor name"written internally so you'll have to open one in a hex editor and replace the old MDL name with the new one, and the "editor name" to something unique (ie "Door UpDown 3 Stone" > "Door Small Hidden 1"). Save the modified PRF under a new name and it should show up in the parameter editor. If you haven't used a Hex editor before, I recommend HXD.
The CP files just need to have the same name as their MDL (ie door1.mdl + door1.cp).
