You can also use Edit>Figure>Rigging>Convert to Weight mapping To use clothing for another figure with your new weight-mapped V3 you need the clothing to fit the base state of V3, which could be tricky - you would need to use DForms to do at least some of the work, plus some scaling and posing. Once you had a fite you would hide V3, export as OBJ, reimport using the same preset (this freezes the changes you've made) and then launch the Transfer utility (Edit>Figure>Transfer Utility), set the Source item as V3, set the target as the imported OBJ and click Accept.
