i would keep it in unless you plan to hand quilt too.
sewing machines can quilt through many layers but hand quilting is really hard work.
if you're going to put this onto the background fabric and thats the end of the layers you should be fine for hand quilting. if you're going to be adding another layer or 2 before putting it on the background i'd consider clipping some of those layers........
either that or start lifting weights in the gym to build up your strength for hand quilting :D
