I would recommend staying away from anything overly peaty. Islay whiskys (IMO) are very much an acquired taste, and do not have as broad an appeal as something milder and middle-of-the-road. I for one, am not a fan of peaty whiskys I'm afraid.

Glenmorangie sounds like the best option! Failing that, many Speyside or Highlands whiskys would make an excellent donation.
