This won't work, for the same reason that we don't get giant insects - as you increase all the dimensions the corresponding cross sections are squared but the corresponding volumes, and therefore mass, are cubed.

For example, a 1 x 1 cube has a face-area of 1 and a volume/mass of 1 whereas a 2 x 2 cube has a face-area of 4 but a volume/mass of 8.
