You an get the Vanya Robe of healing and either the Rose Gold circlet or Vanya hat of healing instead of the Darklight cowl. With materia on it it it's better and you don't have to worry about the combined head-body if you get the Allagan healer hat drop.

It's quite a bit more total tomes in cost, though, so it would take longer. Unless you've already got quite a bit of money already.
