How to Copy and Paste one model onto another

Hello, I am new here, and I figured this was the place to ask. But if I wanted to, for example, turn any human model I see in game wearing certain armor and copy and paste it into a lich model, how would I do that?|||Modifying the MPQ files by doing things like replacing models is a violation of the TOS/TOU and will get you perma-banned almost immediately. Don't do it.|||please delete this thread as it is a banned topic.
