Darren, If you didn't want to worry about the words showing up backwards on the back you could quilt them seperately. Just quilt through the top and batting then add the back.
My Bernina has several sets of letters. I remember making a small quilt for my youngest granddaughter. She had an idenity crisis. It seemed as if she thought everything belonged to her sister. I made her a log cabin quilt with ladybugs as the centers and quilted it by inserting her name in every other row of the log cabins. There was no way someone would think it was for her sister. At the time I didn't know about quilting without the backing. I don't remember what the back looked like. That was probably 9 years ago.
