Epic Fight is rendering entity using own created model.
Male Colonist's model is same with player, so it can be have compat to easy.
But, female's model is not.
It meaning need to convert or recreate Colonist and Raider's model too for has compatibility with MineColonies.

I was success to implement colonist play epic fight's animation.

However, I cannot proceed any further because i don't know using BlockBench, Blender to edit model file.
