I would not take it apart, but that is just my opinion. It is your quilt and you have the option to do as you please. If it were me, I would be honored to have a family heirloom. Not everyone likes quilts and you receiving this quilt may have been because they knew you would take care of it more than any other family member. I would hate for you to deconstruct it if another member is against it. Now if the quilt is worn or tattered, then deconstruction could be warranted.
