Very cute quilt!
You could remove the elephants and do a new applique. What I would do is draw the elephants and use a lightweight backing, then satin/zigzag stitch around, THEN cut out the figures. You could then apply them to the quilt and straight stitch, just inside the satin/zigzag stitching.
You should be able to reheat the fusible and peel the elephants off. If you position the new ones over the old spots, all will be well.
