I was wondering if every country would use the same gender for the same strokes so I looked at the world record differential between all four stroke 100s. It is 5.15 free, 6.27 back, 7.22 ***, and 5.66 for fly. The best option might be for women to swim free and fly and men to swim back and ***. Depending on a country's individual swimmers they might swap fly and back but free should always be done by a woman and *** by a man.
That is assuming you have a fast male breaststroker and a fast female freestyler. There is an idea to go men for the BK and BR to get open water for the women. I think that is not as important as how fast people are. Add up the times and see what gives you the best result.
