Honey Wheats are a good idea, I would do a lb. of high quality honey at flameout, preferably raw from a local source if available. That will be difficult to detect on its own, so I would also steep .25-.5 lbs. of Honey Malt, which does very well when used in conjunction with actual honey. I wouldn't go more than that though, because it will get into cloyingly sweet and overpowering territory. Go with a neutral bittering hop and you should get a nice, delicate honey flavor and aroma.
Alternatively, you could go with 2-3 lbs. of stone fruit like peaches or nectarines. I've had good results from sanitizing the outside of the fruit and the blender with starsan, freezing the puree, and adding it at flameout. This will both ensure the fruit is sanitary and lower the temperature of the wort. Add pectic enzyme if you care about clarity. This works especially well if you use small amounts of something like Citra and/or Amarillo late in the boil, and a tiny .5 ounce dry hop. Helps bring out the fruit character.
