How to do "unified docking": One device to Charge and connect USB to iPad Pro (USB-C) and iPhone (Lightning)

My goal is to build a station for my local dancing school with an audio interface for old iPads, iPhones and USB-C devices (Such as the iPad Pro, Android Tablets and Phones and hopefully the next iPhone) The "station" needs to charge the mobile device and pass through USB-Data. At the moment, it is solved with the Camera Connection Kit (Charging+USB-Port to Lightning), which is plugged into a Power adapter and to the USB-Audio-Interface. However, this solution obviously only works for the old ipads and iPhones, but when a dance instructor comes and wants to connect an iPad pro or - god beware - an android device with USB-C, they completely mess up the system because they unplug all cables and then don't know how to replug them. The question is: is there a way to have a single cable, preferably USB-C that charges and carries data and then a simple adapter or adapter cable to lighting? Are there any USB-C Docks that would work when adapted to lightning or do we need active components when adapting from lightning to usb c?
