I like the current pharoah as is.
Adding more ancient egyptian themed heroes on the other hand should not be out of the question.
Perhaps one with a more easily identifiable motif!
I didin't like the fact of the pharaoh be the clockwerk Goblin. He should be a copy of Dirge, because he is a mummy.
I don't even think he looks like a "pharaoh" but mb that's just me
