There is a nice pic of the two couples (Max/Millia, Hikaru/Misa) with their kids (M&M have two girls, H&M have one newborn) "hanging out" in the "Macross Graffiti" book. It's not by Mikimoto, I think it's by Narumi.
Also, the pic was made before DYRL, so I'm not sure if the "Miku" setting existed at that time.
