It's a little late, but since I've taken over as maintainer and wanted to add a remote interface I've gone ahead and published a new version that should be 'easy' for you to translate with any gender.
Because I wanted to let a remote interface add or entirely set the memoirs, the key editing wasn't going to sit well with me. So I took the path of abusing the plural switch. This also makes it entirely possible to extend the list of genders if more are needed for any language.
I don't think I'll be adding object genders, since different languages have different genders for the same object. That'll require the number of languages with object gender squared of pronoun_id's, and that's pretty unusable especially for adding an object name when you don't know which one to pick.
