Using the pico really is necessary. There isn't a lot of space inside the project shell, and I really don't need the wires messier than they already are.You have plenty of I/O available for buttons. I wouldn't bother with an external micro. More to build, more to debug, more to maintain.
USB CDC looks like a good option, but I haven't been able to figure it out previously.The most straightforward way would be to connect as a USB serial port (USB CDC), and use it with C stdio (or whatever).
