Hi Alex,
Thank you for your question.
Indeed, you should be able to control all the fixtures using the Kiosc app and DaliCores. DaliCores are able to send out both Dali and DMX, and scenes that can include fixtures from both types can be triggered using the messages from the Kiosc app. If you need the DMX lights to be controlled by playbacks rather than scenes, then a CueCore might be needed.
Cheers,
