Oh, I'm glad you asked this. At the Houston Quilt Show last fall I fell in love (or maybe it was just lust) with a beautiful quilt composed of several panels of "bluework" embroidery...lighthouses and a compass design...and bought the patterns, which are prints for tracing. As I checked out, the woman told me that the shop/booth owner had done the embroidery on her regular sewing machine using various decorative stitches. She said that the heavy outline stitches were a stretch stitch and some parts of the lighthouse outlines used blanket stitches adjusted to look like the edges of bricks. The panels were gorgeous and I had not realized they were not hand embroidered.
I have a Bernina 430 and plan to sit down and audition a bunch of different stitches to see how they would look as embroidery stitches. If you do try this with your Bernina, I'd love to correspond via PM or email on this subject.
