To improve jungle variety why not make more/diverse camps?

I think there needs to be a really heavy armor jungle creep that can only be effectively killed by magic damage. Another creep that can only be killed by tanking damage from it where you have to endure damage for a time frame then it can die from smite and it inflicts grievous wounds. This would give more jungle variety and it could create interesting counter jungling since junglers can take other camps quicker.
