You would have to find out which genes are responsible for the development of dinosaurian traits, such as long tails, teeth, a snout and arms, and compare them with those of other archosaurs. Through a lot of trial and error using embryos, you could alter the genes to produce these traits. Horner isn't altering the genes themselves, just their expression.
