native deer densities in the area of the Michigan implants would affect the dilution of the northern influence.
One major problem with that idea is that best estimates are--due to Yearling Buck Dispersal (YBD)--localized genetics are spread outward (and inward) at a rate of at least 20 miles per decade, and in some areas 5 times that (depending on average dispersal distances for the habitat). When it comes to whitetails, genetic diversification is the name of the game. THAT is why they are such a successful species; because almost every behavior they have appears to be about maximizing their localized genetic diversity.
