Tank randoms in DPS gear w/ Tank spec

I'm a kitty when I raid with my guild, but I want to farm badges fast. Is it possible to tank random heroics with dps gemmed and enchanted gear on? Most of my gear is between 219 and 232 ilevel. I would be switching my neck, back, rings, and trinkets. I just don't want to buy 2 sets of T9 gear if I can avoid it.

heroics shouldn't be too bad if you are wearing mostly 232 ilvel, you're biggest hurdle will be convincing people you can tank with your lower than avg HP pool.

You probably can if you have a couple of hp trinket to switch out with your dps ones

Ok, thanks, folks.
