I've been thinking of doing this myself, as i have done quite a bit on the normal machines- top loading bobbin. I bought an extra bobbin casing (and the latest Brother had one with it) and took the tension screw out, because with thicker threads like crochet cotton, you don't need much tension, and it doesn't muck up the top tension. I will buy another casing for my TL18" quilter.
As mentioned, you will have to expect your designs to be on the back of the loaded fabric. The Innova has a special - and very expensive - foot to do this on top, and I believe it only fits that machine, I may be wrong.
I will be looking for a photo of what you achieve.
