so, what difference does it really make how many others have a quilt with the same fabrics as yours? will the quilts ever be together? will your family and friends go to their home and see the same quilt? ultimately the quilt is yours, yours, yours. you cut, sew, piece, quilt, etc. it is yours.
so, i can say that i have done these bom and never worried about it. my work, my quilt and i love them.
