It's still a one hour+ bootpack over rough and exposed terrain at 11,000+ feet. Pipeline is not a run where you want be fatigued before skiing it. So my recommendation would be similar to Highlands Bowl or Silverton: be altitude acclimatized for several days before attempting it. I will keep it in mind for the end of an Iron Blosam week sometime.
