If you load the genesis 2 model (or output model obj from vam) in blender you can load the base colour for each material as an image texture, selecting your converted normal map for torso, arms et cetera on this main layer so you can see them clearly. Then in texture paint mode use a smudge tool on the area of the texture you want to move and then use a smaller smudge brush directly on the model in the viewport to blend them together smoothly. If you drag on the model in the vieport it will update both of the textures at the same time, making them seamless. You can then click the word 'image*' above the texture window and 'save as' for each image, don't save over your originals in case you made a mistake when blending them together. You can then either load the defuse, spec and normal maps in the shading tab of blender to view them, or just load them up in vam to see how they look. There are loads of texture paiting tutorials for blender on YouTube if you need help. Good luck.
