H-m-m-m-m. I recently wanted to make a quilt like your daughter requested--I used a thrift store comfort for the filling and tied the layers with buttons and perle cotton. The comfort was already stitched so the tying was as much decorative as useful. Yes, it's a comforter but with a pieced top.

If you want the quilted look, layer your top with a thin batt and backing and quilt the three layers. Use the resulting quilt as the top layer of an "envelope" or casing with your choice of an additional backing. You would only need to bind one edge--the other three would be sewn to the second back, right sides together and the result turned right-side-out. Insert a comfort. Button or velcro or tie closed. So easy to wash if the comfort is removable. With the batt and lining, the comfort shouldn't show through. Voila! A nice, thick quilt of the kind your daughter desires.
