Under-tournament, Unreal tournament with undertale stuff

[lonleyglobe0]

Hi I need some help replacing all the models and textures in the unreal tournament 2004 demo with my own undertale models (For example: Replacing the thunderCrash with the dreemur family). I also need hit boxes changed because of stuff... So i need player models, Static models and ground/Wall/skybox textures changed along with hit boxes. If you could point me to a program that is easy to use and understandable for idiots like me, I would be happy. And before you start yelling copyright alert, this is for personal use and I am only doing it to the demo.
