Can't help you out with the Mkids but I am working on a new kid figure made from V2. As you can see, she can be made to grow from child to adult. The Mkids clothes can be tweaked to fit her fairly easily (atleast the items I downloaded from PWFW worked with no problem) I have also been able to rescale the V2 stuff to fit her, with only the chest area being a problem (need a no breast morph to fix that). Anyhow, I will be posting her to Free Stuff shortly so you might want to keep an eye out.
