Im not too sure about this experiement. Ive had a quick look over it, and there are a few problems in performing the experiment to begin with.
Firstly, there are a number of kits available for genomic DNA purification, as well as the "old-school" methods which can be time-consuming and can shear the DNA. Look at QIAgen, Promega, most of the good big companies would provide good kits for extraction.
The transfer the DNA into the donor cell, well the donor cell generally has to be competent, and DNA transfer into bacterial cells (well in the case of plasmids anyhow) is generally achieved through either electroporation or via heat-shock. The number of positively-transformed cells would be very low, i would imagine, if it is even possible with a whole string of genomic DNA to begin with. Id also imagine that you would probably have to use a vector of some sort to deliver the DNA into the donor bacteria.
Ill look a little further into it for you (at work at the moment, and my brain is a little fried) But changing species, well.... I wouldnt place my bets on it....
