I also think taking it out would be the way to go. You might be thinking that it's a lot of work to take it out, but I had a large lapquilt completely finished.....and like you felt it didn't look right. I put it aside for awhile and one day while watching TV just sat and used the seam ripper. It didn't take nearly as long as I thought it would...I then just re-sandwiched....and it turned out great.
