mgon: Give it a little more time. I didn't date my entry, but I gave my overly honeyed beer maybe an additional 4-8 weeks after 4 weeks fermenting and 4 weeks conditioning followed by a week in the fridge, and it was certainly better. Still thin though, but better.
I had used ~3 3/4 lbs of honey in the fermentor after a week of fermentation in a 5.3 gal batch.
I don't add any crystal malts to my honey wheats, though I have also used a bit go honey malt. I do, though, use a little crystal in my blondes. I don't recall how much honey you used, but my suggestion would be to keep it to around 2-2.5 lbs per 5 gal.
My latest honey wheat (6 gal batch), and about what I feel is a nice balance between plenty of honey without becoming too thin, and yes I taste the honey, and it's very much like Blue Moon's honey wheat, was:
3 lbs wheat DME (2 lbs @ FO)
2.25 lbs honey (FO)
1.75 lbs 2-row
1.75 lbs soft white wheat berries
0.5 lb honey malt
0.4 oz Willamette & 0.4 oz Mt Hood @ 45 mins
0.8 oz Willamette & 0.8 oz Mt Hood @ 20/5 mins
WB-06 dry yeast fermented colder (low 60's)
This wasn't as hoppy as I had hoped, but was still a good honey wheat beer.
fsr: If you add the wild honey after a week of fermentation I'd think the yeast would have plenty of time to have done their main job, and would have a thousand legs up against any wild yeast. But it may also be something you wouldn't want to use as a washed yeast as it may have some wild yeast going which can bite you later on.
I wouldn't add honey any sooner than 5 mins left, but really prefer flame out these days. That's plenty to kill anything in it I'd think. No qualms with adding it after fermentation though, but I like numbers, and it's just easier to figure it out at FO.
