Interesting setup, but possibly sensitive to noise as there are quite 'a lot of' analog wires through a not small setup.
Another possible approach would be have 8 channel ADC e.g. MCP3008, each one used for four joystick/ eight potentiometer. Place em in close proximity to the potentiometer to reduce analog noise capture.
These 10 ADC chips could be distributed to the two SPI channels of RP2040. Placing the pico in middle of the setup would minimize SPI wire length.
