My own quick and dirty way to do it:
Take the mother's race as base creature. Apply partially the half-dragon template of the father; add only the new immunity and breath weapon. Rather than once a day, the new breath weapon is at will (just like metallic dragons have a choice of two breath weapons, it just add them a choice). For the aspect of the beast, merge both races, using the mother's variety as the predominant one. Colors may look like mix of colors or like alloys, or anything you think you need (it's potentially weird for cross-family hybrids like gold/amethyst or red/crystal dragons, for example -- I don't think there's a great probability of seeing a metallic/chromatic crossbreed).
Hmm... Red/Shadow dragon... Fire and shade mixed in one... Cold fire causing negative energy damage... Here's the Balrog dragon !
