No, the full mods are not interchangeable. Only the the meshes and textures can be used in either game and require a manual install. If you think the textures for the base type 3 look good, I would guess you have not seen Mojave Delight or Beware of Girl. I have used both. I really dislike MD, but BoG isn't too bad. However, I prefer to use T6M with the Real Feel textures, as well as the Type 3 narrow shoulders mesh fix, since T6M is just a modified Type 3. However, I just wanted to know if other Fallout 3 body replacers worked such as (Just using this as an example) Type V. However, I do appreciate you stating the "Meshes and textures" bit, that's generally how I install my body replacers and apply any texture changes.
