Mayo on grilled cheese is actually a thing, and you probably have already had it without even knowing it. You don't like, actually see the mayo, it's spread on lightly in place of butter, so by the time the thing is cooked, it just looks like any other grilled cheese. And then there's certainly no strong mayo taste, it kinda just tastes like a slightly stronger butter. Sometimes diners will use it because it doesn't burn as easily as butter does.
