Unlikely this could ever be done. We share too much of the same firmware for something like to be possible. The average human genome has about 4-5 M single nucleotide polymorphisms (SNPs) - rate in the order of 1 SNP / 1000 bases. The rate is much lower in functionally important parts of the genome because those tend to be under evolutionary constraint / conservation.
