Absolutely. I made a Berlin Wheat and didn't come anywhere close to my efficiency and ended up with a 3.5% ABV beer. I just waited until right after high krausen and poured 16oz of clover honey right into the primary - wow did that yeast take off. Since it was a wheat, the slight honey flavor worked out well.
If you add it to the boil, even for a few seconds, you can eliminate all honey FLAVOR and just retain the sugars. No need to boil though, bacteria does not live in honey. It does ferment out pretty good though and will dry your body out on the brew a bit.
