External usb c port with pico as "Bad USB"

Hi i am new to using the pico but have used arduinos before, i want to make my own version of a flipper zero and im trying to make the Bad USB feature but i dont want to plug my pico into my computer while the battery is plugged in, so i was wondering if it would pe possible to control an external usb type c port that i can use my pico to send the Bad USB commands. Also to use the usb-c port as charging for the battery. I hope this made any sense, Any ideas are appreciated!

Heres a really quick and messy scetch

noice pic

and this is the problem with creating stuff like this 😭, it's called karma

firstly before I even consider helping you, what are you going to use this for?

lol dont worry, i have always wanted to just try to make one since i saw the flipper zero, probably just going to disassemble it and use for other projects as i dont have any use for it

its a pico w so im going to try to make a wireless robot arm after this, but i dont have the money for it rn

I mean you can control the Pico kinda from the gpio. it's mostly just like things to run the script and things. you can do this without your pc

and then use your computer to charge the battery and power the Pico. like mentioned and shown with the absolutely beautiful diagram
