As I said before, they might have them as extremely rare item drops. (like the "unique item" drops for creatures - see the Achievements page for examples) - but for now, they aren't. I was wrong about the Wabbajack and Fork of Horripilation being tied through the Fighters Guild questline because I have done a few quests for the Mages Guild and found out they are tied to it. Also I think Meridia is in the game as well and involved in the main story.
