No:
digikam uses as naming scheme for the sidecars <name>.<ext>.xmp, where <name> 
and <ext> are from the image file. Raw, tiff, and jpeg filse have different 
extensions. So just a simple copy won't work. Even if you have the 
"compatibility" option active (that one allows reading of <name>.xpm files).

In addition, you will have to verify the contents, some things in the sidecar 
for a raw might be absent from a jpeg sidecar (and vice versa), or have a 
different content. (I don't create create jpegs with digikam, and they are 
rarely in the digikam collection, so they don't get tagged by digikam in any 
case).
