That might work.

To make it work to USB spec you should really also have a USB lead plugged in that has two 15K resistors from D+ and D- to GND. With this board you can't connect them any closer to the chip but that probably won't matter.

If you are getting the 4M version you may find that they will clock faster than the 16M ones.

Incidentally, the RP2040 stepping number is B0 for the original chips.
B1 has changes to the boot rom on the chip which enhance the floating point routines amongst other things.
There is now a B2 but it's not in my datasheet.
