You could always ask if anyone's done this at AerySoul's forums.  That's where they do all of their customer service.  There is a newer Hanyma outfit here in the store that is for V4, as well as a texture set for V4 to make her more "androidish".  
I don't think they've converted Yaara for V4, and you can try your hand at using morph transfer programs (I use Morphing Clothes, others have had good luck with other programs) to convert the older Hanyma outfit to V4, or the new Soulbringer outfit to V3.
