The Suggestion : A config for the final boss

Would it be possible to include a config that allows to specify which mob spawns instead of the "final boss" (so in that purple box at the top of the white castle).
As of now I believe that there's still a buffed goblin as a placeholder or something (or maybe just nothing). Personally I would prefer for the specified mob to spawn only when a player enters the purple cube (It was the case for the goblin if I remember well...).
So put simply : I would appreciate having a config option where one writes "mod_id:mob_id" and voila, that's the final boss !

Why Should It Be in the Mod?

Not having a final goal just doesn't quite make it for me, so I thought that it could be a good idea to have a (boss) mob from another mod as the final boss !
