Glad to se you got somewhere with this, to be honest you got further than most Devs do on here.
Re Animation and clipping.
Not sure why clipping is an issue! If the clothes have the correct shaders to block out the body parts there should be no clipping. If they dont have the shader texture, they can be made easly from the material textures.
And Animation, thats quite specialist. What I would sugest is you contact a couple of animators on Loverslab (SkyrimSE or Fallout)and ask to use there base anims(As the Lifeplay Dev did). You may need to pay them a small amount, then drop the IK and just alight actors in containers, so they fit together properly.
Also not sure what happend to the Vag models I gave you, If you assigned the base model textures to them they should be seemless, they where for me!
Anyway glad to see you finnished it, will try it out later.
