Take a look at the parts list. Any part that is right/left specific will need to be swapped for the opposite. You will need the opposite of; [Black Wedge, Plate 6 x 2 Left](https://www.bricklink.com/v2/catalog/catalogitem.page?P=78443&idColor=11#T=C&C=11), [Dark Bluish Gray Wedge, Plate 3 x 2 Left](https://www.bricklink.com/v2/catalog/catalogitem.page?P=43723&idColor=85#T=C&C=85), Light Bluish Gray Wedge, Plate 2 x 2 Right, Light Bluish Gray Wedge, Plate 6 x 3 Right, Light Bluish Gray Wedge, and Plate 12 x 6 Left.


Most bricks can be swapped left right except the wedge plates. The Adidas shoe gives you extra pieces so you can make the left or right shoe, and I believe all the extra pieces are wedge pieces, and one printed piece that is reversed.


I ordered these pieces for not too much on bricklink to build the mirror. Not possible out of the box; you might get lucky with your loose pieces.


Theoretically, that should be possible with no additional bricks.
