How to create a kid in Daz who looks like their parents

Okay, a potentially weird one: anyone have any tips/best practices on creating a character/figure in Daz who looks like a blending of two other characters? That is: say I wanted to create a character who looked like the child of Michael 8 and Victoria 8, is there any way I could do that without simply eye-balling it? 

Obviously, it'd be easy enough to make a male figure who looked a little like Michael 8 by tweaking some sliders (or a female figure who looked like Victoria 8). But is there any way to make that male or female figure take on some of the characteristics of a parent who's of a different gender?
