Keep in mind that without additional effort the potentiometer are not floating (isolated from each other), but the analogue voltages need to be in some range around a common GND voltage.
I don't understand that, could you describe it in more detail😂
For the CS-signals, there are IO expander with more than 16 bit available. E.g. PCA9698DGG,512 or use some FPGA chip.
When I search for this chip, I only find one with an I2C interface

After further research I unfortunately found out that the chip I was looking for (MCP41HV51) in the 10Kohm version (which I need) does not manage 24mA but only 12.5mA. Do you know of a chip that can handle 25mA at 10KOhm and up to 26.5V?
