It can be done if your healers have balls of steel. **pops collar**
Put your better healer on the Morchok side as they'll be taking more stomps.

I wouldn't want to do it that way the first time. It is alot of damage, and since healers have to crystal soak, they may have to move at a bad time. Some healers I believe have an easier time one-healing a side than others but I don't know who to recommend.

Honestly, it's not too bad. If you have a resto druid, I wouldn't recommend it as it's difficult for a druid to heal everyone up in time for the next ability. That said, if you DO have a resto druid, or just don't have 4 healers in the wings, this can easily be done with three healers. Put one healer - someone strong, with quick AoE healing abilities as well as good single target - on Kohcrom (the twin that casts less stomps). Put your other two healers on Morchok. It's actually very easy to do this way - the more difficult side has the coverage of two healers, while the less difficult one isn't being overkilled by having too many healers. It's especially good for while the fight is progression or not a sure-thing. Once you're comfortable, then you can move down to two.
