The main issue with the rp2040 that I can see is the CAN bus, and the lack of 5V tolerant pins.
CAN bus should be doable with the help of the PIOs, but it's fairly complicated. I have not seen any full or even partial implementations of CAN bus on the rp2040 PIO. Interest is big so one will most likely appear, eventually.
Other than that it would be easy to CAD a new PCB and swap out the STM32.

Yeah, I have had a look for a PIO based CAN implementation and it doesn't seem like it exists yet unfortunately but there do seem to be a number of people interested in it. Hopefully its just a matter of time 😄
