to make sure there's some diversity at the leadership level and that it's not a bunch of people who look exactly the same.

Let's be honest here. You're looking for a specific demographic, and you're not actually concerned with the composition of the talent pool from which they were hired. It's an increasingly popular de facto anti-meritocratic movement and I don't think trading some amount of competence for diversity at social scales will actually be good for society in the medium to long term.
