In my past I got to learn a language that is gender free—even more so than English. It’s Farsi, the language of Iran and Afghanistan. If getting rid of language genders is important for women’s equality, then look to Iran and Afghanistan for your inspiration.
They may not have pronouns like ‘she’ or ‘her’, but I’m sure they have words for ‘woman’, ‘mother’, ‘sister’.
That’s not a gender-free language.
