Pretty much what Worships said, that would be like having a Mehrunes Dagon Shrine quest in Oblivion. The whole main questline acts as a Jyggalag quest. :P And I'm not too sure about a shadow HoK, I mean, they're Sheogorath now. And a better reward for a Jyggalag quest (If there was one) would probably be the Sword of Jyggalag.
