In theory, yes. In fact, they did it that way in Java, just as they use
the 3rd person keywords "extends" and "implements".
In practice, you would meet a lot of resistance if you tried to introduce
two keywords as similar as "throw" and "throws" into C++, when they can
never even appear in the same place.

There are no other keywords with a purpose comparable to "requires".
