Swap characters in Test your might, sight, strike?

[Xyl3to]

Is there any mods/tutorials that can replace the characters being used in The Test your sight, might, and strike game modes. Id wanna to see how all the unique animations would be done on the different characters. Not necessarily looking to add new models to them. Id just like to replace the character used with a different one already in game. Maybe something that can just live swap the character out? I dont know I’m new to modding mk9.

If someone could please let me know if there’s a tool to swap character models in game. Or tutorial on how to replace the models being used in these game modes that’d be much appreciated.
