I did the same thing for my 2DS XL, but instead modded the device with a non-PD USB-C breakout board. Works great with both USB-PD and regular USB-C chargers and cables. https://nullsum.net/posts/usbc-mod-new-2ds-xl/

Now, in the days of complex calculated power delivery negotiation, a hack like this would be impossible.

The only devices I've seen _require_ USB-PD are PC's. All the modern phones, headphones, and gaming handhelds I've seen with USB-C do not require USB-PD and charge just fine with a USB-A to USB-C cable.

Better yet, these devices all use a standard USB-C port instead of a proprietary one. The only gotcha is that some USB-C devices break spec and don't work with some USB-C to USB-C cables. Both the Pi 4 and RG351P suffer from this.
