I stumbled over a similar project in a German Maker Newspaper.
The concept behind this is explained here. For me this sounds awesome and I have everything for it on Board.
With the ESP32-S I can even use the Board as a MassStorage Device. This enables changing Scirpts directly on the Keyboard on the go like using an USB Stick.
Additionally I have a Micro SD Card Holder ready and good to Go.
