Well they have been a bit busy to try that, although Dean did attempt it in "Appointment in Samarrah" basically its next to imposible, Castiel as a Seraph (second highest class of angel) botched it up, and was unable to get his soul back. The only one who could swing it without any chance of it failing is God, Death (and possibly the other horsemen) but God doesn't really interfear much, Dean already asked Death and he refused, and the other Horsemen are in a coma now, and even if they wake up, its unlikely there going help out.
