Notes on Racial Phylogeny, a restoration skill book, states that the child takes on the characteristics of the mother, with only slight visible genetic characteristics of the father. It also states that "relations" between Argonians/Khajiit and Humans/Elves are mostly inconclusive, that is the author is unsure if the offspring is fertile. So it seems that it would be fairly easy to program, though the aging is a problem.
