Add support Epic Fight mod

What do you mean by add support? it should be supported by default

I'm using your mod via Connector in place with EpicFight, but it doesn't fix custom armor with shaders

What do you mean by add support? it should be supported by default

Again I dont know what you mean by fix.
In any case I dont officially support connector, if you have an issue you can show how to reproduce with fabric I can look into it.
