I decide to make with KISS rule at the first place.

For slave outputs I decide to make chained shift register powered with SPI, when I want to make it more complicated I can add small CPLD/uC to keep more registers and be more "intelligent"

I think also about adding extra lines for UART and CAN buses

First test is here:

Next step is to make this idea more robust....
