I really appreciate the enthusiasm. There is one big issue with your contribution with respect to the project. It won't work for existing users to migrate to and is not tested against traditionally supported infrastructure.
To aide existing users I've had a summer student put together a mostly complete effort for transitioning to Django 4.2, Python 3.12, with modern language and localization support. The result requires testing against actual clinic sites, with tested upgrade workflow. Would you be interested in helping? I really hope the answer is yes.
