The fight is a two heal fight...

I'd say it's a three healer fight that may also be doable with two depending on your setup. Most HoF fights seem designed for three healers (as opposed to MSV, where Gara'jal, Spirit Kings and Will are all easier with two).

Is it a bad idea to use Mages and Hunters instead healers to kite him

Yes. Healers won't like kiting, but the enrage timer isn't very forgiving. Something we learned, however, was that healer-to-healer swaps quickly could prove fatal, as you often have to do the swaps out of range of others. Two healers out of range of most of the raid at the same time equals wipe. So have two DPS and two healers alternating. Use whichever DPS can deal the best damage while moving.
