This whole discussion is based on the proposition that height is determined
by genetics. This is not true. The average caucasian height was 5'4" only
a century ago, and has varied up and down with diet for centuries. It
takes at least two generations of changed diet to express fully, probably
because of maternal influences.

Put them on a beefsteak and bean diet for two generations and then measure
their height. Until then, you have no data whatever.
