Definately need that MilCat, whether using Mia or making your own. What you'll do, as the tute will tell you, is load V3 (or V3-V2 in your case) and the MilCat, hide V3's head & other head parts, hide everything but the MilCat's head then move/scale the MilCat until the head "fits" onto V3. Note the quotes on "fits". It's not going to be perfect. LD modeled a new neck with a skull base for Mia. But, most hair will cover any gaps in the mesh, plus there is postwork. :) LLLLLhiannan ;D
