Thread: Warhounds?

Quick thought, who thinks I would be in for a potential rule-crazy, hissy-fit if I were to use fantasy Warhound models as my 40k Flesh Hound models? I would put them on round bases, of course. And I can't be the first person to do this so I'm curious if someone has some first hand experience with this kind of thing?
Would this personally bother you??

Also, for the Chaos, general hissy fit story thread too. Let's hear some good ones.

As long as they are approximately the correct model size, nobody will care.
