Unlikely, although I am no expert. But every cell in your body contains a complete copy of your genome, so you have to fix much more genomes in a grown body, then in an embryo or even only the one cell that is a germinated egg. Also, as Jumpin noted, the genes are basically recipes for enzymes, that in turn control certain developments in you growing up. So it could well be, that changing the genes after the fact will not have any effect or not a substantial one.
