Hotel Le Kilmandjaro on the edge of the piste in Courchevel 1850 is already a pretty upmarket choice but if you really want to hit the heights book into one of its two private chalets: Chalet Les Sorbiers [Chalet Les Sorbiers] or Chalet Totara [Chalet Totara]. They both come complete with your own butler, chef and chauffeur which makes them some of the most exclusive choices on the slopes.  Book for a week, then name drop your residence in the lift queue for real Courchevel cache.
