Some parts of it, very likely. The shell is just linenoise with some glue code. How are things with ELF loading on rp2350, I did not check. May be possible, the question is, how much effort. In ESP-IDF that is a standard component now.

rp2350 supports freertos, so a similar port should be fairly trivial.

The io DMA code is a little special on the Pico. Very capable little chip. =3
