Hi emcee,
The definition of a quilt is wadding stitched between layers of fabric. Nowhere does it state that this fabric needs to be pieced or that it cannot be a panel. In fact, many traditional quilts are whole cloth quilts where the stitching is the star of the show. There is nowhere in the world where it states using a panel is a cheat or that a quilt made with a panel is a cheaters quilt or not a quilt. So, my opinion is, go get those panels, enhance then if you wish and Quilt On!!!!!
Hugs
