Hi! Thank you so much. Absolutely, you would be very welcome to translate it. You're also very welcome to add supplements too! That's very flattering that you're interested.
I have a plan for faction play, based on a stripped down version of Blades in the Dark, but there's no reason you shouldn't make your own version.
If you are using my stuff directly, please just credit me. Also, make sure to credit Jason Tocci who made the original 24XX rule system.
:)
