I have my dog ( a beagle) with my girls, she doesn't have that "drive" though. You pretty much need to get your dog to the point where he doesn't fear her or like her, but rather is pretty much indifferent to her. From there they might grow to like each other, but they are 2 completely different species and 99.9% of the time won't really bond so much as tolerate each other
ETA- accidents happen when fear and the prey drive get together, so even though you think he won't hurt her, please watch him closely.
