It's a bummer you can use the CAN library, I hope you find a way around that. I really like the idea of having that nice display on the CAN bus of your "airplane".

It's a lot of hardware and a lot of pins to deal with. Is your goal to stick with the original technology?

I see you lower the count by using the expander.

Maybe we can work together here to create a design that uses the same display but avoid that the microcontroller needs to drive that many individual I/Os.

CAN alone should be enough to tell the display what to do. The rest could be added to the display unit by adding a single CAN-aware microcontroller close to the display ...

Sounds like you need to do a modified CAN bus and use software to ensure that there is only one master control.
