If we're going off the Timeline Jyggalag would have come about, 2 years after the Oblivion Crisis so if he took an interest in the Thalmor I would imagine he would have sent in some of his own troops along when it came time for the Great War. At the very least its an interesting theory, but I would imagine that if he had any sort of hand in assisting them we would have seen something by now in the form of troops, or even the weapons they use, or some of the higher members worshiping Jyggalag for the help, something.

If you're suggesting simply that he is manipulating the upper echelons of the Thalmor, I could see that being somewhat possible. But even in that instance I would imagine "revenge" against the other princes who turned him into Sheogorath would be higher on his list of priorities.
