Hello, and thank you for you post here on our Forum! Yes, we are indeed working on a kit for the Diagon Alley set-- you can read about it here. Unfortunately due to unforeseen supply issues in 2021, we've had to push back most new sets, including this one, into 2022. You can read more about the reasons here.
If you have specific features you'd like to see in a kit, please let us know on the main Forum post.
