Assuming by "jutting pieces" you mean the pins, yeah, I could see that being difficult ultimately to manufacture into the 3.5mm jack configuration.

But translating each pin to a "band" (sorry I'm not very technical myself) on a jack with the form factor of a 3.5mm pin should be doable. You'd probably need 5 or 10 bands since (as I understand it) USBs use a 5 pin connection (again, as I understand it, most devices mirror the 5 pins on each side, but some more advanced/specialized USBs utilized the USB-C connector as 10 pins, hence the possible desire for a 10 band jack).

Again, I could see that being difficult to manufacture, but not impossible, and especially if it became a standard package. Might need a bigger jack than 3.5mm though.
