how I do it:
- "delete to trash" the unwanted jpegs
- write a small script that searches through the trash folder for jpegs 
and deletes the raw files with the same basename; then delete the jpeg 
in the trash (or move both to another, private trash)
like this (bash script):
cd $DIGIKAM_TRASH
files=$(/bin/ls -1 *.jpg )
cd $DIGIKAM_ROOT
for i in $files
do
     DNG=`basename $i .jpg`.dng
     JPG=`basename $i`
     find -L $PROOT -name $DNG -exec mv -fv {} $TRASH \;
     find -L $PROOT -name $JPG -exec mv -fv {} $TRASH \;    # doublettes
     rm -f $DIGIKAM_TRASH/$i
done

like this:
cd whereyourjpegsare
files=$(find -maxdepth 1 -name "*.jpg")
for i in $files
do
     rating=`exiftool -f -rating $i | awk  '{print $3}'`
     if [ $rating == "-" ]
     then
       rating=0
     fi
     if [ $rating -lt $min_rating ]
     then
       DNG=`basename $i .jpg`.dng
       find -L $DIGIKAM_ROOT -name $DNG -exec mv -fv {} $TRASH \;
     fi
done
