This has been proposed in the past, multiple times, and hopefully, it'll be feasible at some point.
Ideally, we could have male names only, female names only, all names for each type of commander so that for RP purposes we could do every sort of society - maybe women can serve on ships but not on ground forces, or maybe women are scientists only, and so on. Then we should also be able to set the minimum age for service also per type of commander - maybe my species reach maturity at 150 instead of 21. This would also support custom commander systems, like people who have 12+ ranks as they model both officers and non-commissioned officers - as you could then have your navy commanders start as Ensigns at a young age but your administrators start as middle-aged middle-managers.
Even better if we could have entirely separate name themes for different commander types. Maybe my species is actually two different species living in symbiosis but tasks are separated - or maybe my United Earth Alliance draws administrators from Japan while military leaders come from Sweden.
All of this can be RP'd by the player, of course - in my current campaign I only use commander last names since Victorians would not send women into battle but I can't be bothered to change their first names for ten countries - but having them in the game would make things little easier.
