I think you’re missing a trick here… given the risk of death it’s imperative that regardless of how weird the criteria get, if they have a meaningful impact on the risk of death it makes sense to seriously consider it in the selection process for the crew. It’s not sexist or feminist or misandrist or anything of the sort of you have a big table of numbers and the summary is “risk of death by crew composition: 3 men %A; 2 man 1 women %B; 1 man 2 women %C; 3 women D% If that table has D as the lowest number by more than a single percent or two then it just makes sense. Even if the average risk is 50% likelihood of death you’d want to pick the 48% risk crew composition regardless… Or you would do the NASA Orion program thing and spend years overdeveloping your spacecraft to get you to under 10% chance of hardware failure being responsible without putting anywhere near as much money into studying if the Astronauts are going to stab each other or any of the many soft and or psychological risks that could result in death on a 2-4 year mission to mars… for which Orion is blatantly unsuitable if you ask me.
