You can't simply copy one code file and expect that the game will load the copy as well. There is more than this file to define and register entities, for example the LOTREntityRegistry class.

I think you can't solve this problem without some coding skills. And it's probably much easier to modify the morph mod than to change the whole entity and spawning system of this mod.
