How do I replace an in-game wrestler with a modded one?

[Donny Trump ™]

Hello everyone, so I bought 2K18 on PC a couple weeks ago and have been playing around learning how to install mods and shit. So far it is tedious but satisfying. I've figured out how to install modded wrestlers as new characters, but I've yet to figure out how to replace in-game models with others. For example, I recently downloaded Unbreakable138's Giant Bernard mod and I would like to replace the in-game Albert superstar with Giant Bernard. If possible even change the name? (which I am also clueless on how to do) I do have some basic knowledge of Custom Character Tool, Data Editor, WWE 2K18+ and a couple other programs, so I'm not a complete novice, but I don't really know how to go about getting in game superstars replaced. Any help would be much appreciated!
