Nyx was originally designed as a "Female Excalibur" but was later changed into a seperate Warframe. You can still see the resemblance in their designs.

However, as another Lone Tenno stated, the Warframes have set genders because that's how the lore works. Besides, a Warframe named Valkyr won't work as a male, as the name is based on the word "valkyrie", warrior women from Norse mythology.
