1- Yes you can use Saluda with V2 - the geometry is the Millie version of Victoria, but it is the same as Victoria 1/2 except for the 3 texuring differences. 2- The genitals are morphed rather than a prop, but she does have genitals and because she is based on Millie, they are textured. 3- She is based on Millie. If you mean, the JCM from MillieJCM - yes - you would want to combine the Saluda morphs with the JCM, just as you would want to combine the JCM with any character you use.
