Not to my knowledge, but I just think it never came up - people argued that both of them would keep gapping to other universes, but never the matches iirc. Still, Yukari's not omnipotent like the Host is and hasn't demonstrated the capacity to create an entire existing universe (though she has been shown to pull people into hers I think).
I see. To put it another way, think of The Host like Animal Man, except with the notches turned to 11 - to explain this if you don't know him, Animal Man's family died once. Since he was a pal with the writer (as in the actual writer), he convinced him to write them back to life. The Host has the same ability to contact The Audience, but this doesn't mean he can go and supersede their will by editing the bracket, as they (we) are an Aleph One to his Aleph Null omnipotence. Editing a character out of existence by flatly deleting their fictional universe is within his powers. Deleting the author or readers is not.
