Thank you !!!
1. In short I don't have the skills. I only know how to work on existing textures.
2. Yes I know. I fixed it on one iteration but I didn't like how it looked, weierdly looks better with the clipping (in my opinion, don't know why, something about the body proportions). Now I don't have time to work on it and also I'm kind of burned out with modding. When I will have some time I will give another shot on fixing it.
