That's actually a really good theory but

1. Altmeris culture makes daedra worship impossible (hence the exile of the chimer, orsimer, ayleids and maormer.Only a select few manage to worship daedra eg Lord Naarfin.

2. Also all Daedric Princes crave worship but if the majority of Thalmor don't realise they serve Jygallag it might not be as potent.

3. Jygallag is said to  be weaker than most of Princes, maybe as weak as an aedra. The Thalmor did recieve a suspicious amount of support from the Aldmeri Dominion leading up to the Great War but the Aldmeri Domnion and Thalmor have always had the capacity to defeat the crumbling empire so it isn't that much of a stretch.
