You mean like Vlitch Cleaver from Mod of Redemption and Imperious from Qwerty's mod. I thought that you would put like default cube as the final boss and called it like "Spirit of Eternity" because of 2.2 is taking forever, maybe like other levels that are harder, anyways I still thinks it would be cool if Blade of Justice becomes the final boss. Also just saying, if you planned to add Blade of Justice as either a boss or a weapon, I would like you to make some form of easter eggs about King Slayer III sharing the same song as Blade of Justice, it would be cool.
