If you are still working on this, I'm trying to start authoring chemistry questions in conjunction with the LibreTexts project. I would definitely like to use some of these features. WebWork is one of the technologies they incorporate in their ADAPT platform. I would love to share work as widely as possible, and to avoid duplication of effort as much as possible. I have a ways to go before I'm producing significant numbers of questions. I'm trying to develop the technical expertise needed, now, and I am interested in what you have accomplished, here.
