Fill my stable

So, I decided on what I want to do for Stampede, but I need some help. Is there a list of tameable bosses (raid or dungeon) anywhere?

I am looking to fill my stable with boss mobs, preferably with unique skins. What I have in mind so far:

1) Chromaggus
2) Chimaeron (well...hopefully +) )
3) Lord Kri

Any other dungeon/raid bosses that I am not thinking of, preferably those with unique skins or color schemes.
Garrosh seems wild enough to be a beast.
