A bit of information that reinforces my point, and is well sourced:


 * "It appears all members of the Dwemer race were simply removed from the world. When the previously untouched Dwemer ruins of Bamz-Amschend in Mournhold were rediscovered, numerous piles of ashes were present next to weapons and armor, on chairs, and in beds, suggesting the Dwemer's bodies were suddenly reduced to ash in some way. In 4E 201, Arniel Gane, a researcher at the College of Winterhold in Skyrim, attempted to recreate the circumstances of the Dwemer's disappearance after obtaining Keening, one of Kagrenac's Tools, but vanished suddenly in the process, strengthening the theory that Kagrenac's use of the tools was the cause of the disappearance. Some scholars still resist the notion that the Dwemer disappeared all at once."


 * You may find this here.


 * You'll notice that nowhere on that lore page, nor at the ones over the Imperial Library mentioning your theory as even being one worth debating.
