I mix hand quilting, machine quilting, and machine embroidery on my quilts all of the time. Like you said, the hand quilting will not really show in areas anyway.
Machine quilting is no longer thought of as the 'fast way out' and inferior to hand quilting. I have many friends that can no longer hand quilt and they still want to make quilts, machine quilting is easier on the hands.
In a baby quilt contest in a magazine there were 10 baby quilts submitted. The 3 winners were all machine quilted, the 2 hand quilted did not receive an honorable mention.
But hand quilting is still my fav!
