[Skin]Could Infernal Amumu get a small tweak to its voice?

Although I really want the skin, I personally do not feel like the skin is 1350rp tier. Also the tweak would make it much cooler. Just making it sound actually a bit more infernal (like nasus) would be nice. A skin with the Infernal in its name yet sounding like a normal depressed child is just odd to me.
