The serial steppers are nice because they are easy to setup and they are also very quiet. I dont know if there is an fpga firmware for it thought. The SPI ones, someone has done a custom firmware to work with those.
What is W13 doing? Is it just for swapping between the usb or the green connector?
Consider adding a jumper that can disconnect power to the FPGA or separate the 5v rail between FPGA and RPi5. I found it convenient having a separate jumper for that, incase you needed to either separate the power between the 2, or if you need to reset the MCU/FPGA, you dont need to turn off the RPi
When you are done will you post the design on that easyeda website so I can clone it to modify it? Im also hesitant about a 1 board thing, but I wanted to make something with a swappable MCU/FPGA , and the formfactor looks pretty decent sized.
