I'll admit I'm not familar with that mod, but I have seen a few things (that I know come from mods) that I wouldn't mind being added - such as an ultrasound, and more reaction options than "yay a nooboo" from the parents (mother included). I don't know about miscarriage, as it is a big point for many women and does go against the sim's wacky whimsey. As for skin overlays... I could have sworn that they added stretchmarks with Growing Together, but I could be wrong (not on my main computer at the moment.) Probably not quite the same thing as the mod, but likely as close as the Sims Team is willing to get.
