More special views in spectator mode

If your in spectator mode you can go into mobs and see what they see,some mobs even have special views and it would be cool if there where more. It is awesome looking through the eyes of an endermen and seeing the world inverted or seeing everything green as the creeper. If mojang added this then maybe you could see like the wither with undead things in green and alive things in red or see as the guardian with one eye like with the telescope.
