Brrit - It's not a clone, but if you like In Heat, you'll like it.
The yeast is really what makes the beer. If you use something like 3068 it'll come out like a hefe, but you could also use something S-04 if you want an American-style wheat, or a Belgian Wit strain. I've fermented it with 3068, S-04 and 3463 - Forbidden Fruit and it came out really well every time. It's a pretty versatile base recipe.
And like Oldsock said, watch your ferm temps, and also don't overpitch.
